I love how you guys are just excited with every car that goes though the garage, whether its a 600hp Corvette or a 200hp civic and anything in between. Much love from Indonesia. Edit: Spelling
Wow 220 whp all Bolt ons and no 3in exhaust just just amazing.👏👏👏 I can so relate to this build. Since I have my own 8th gen with similar mods can wait to see more
You guys are still using the nsx wallpaper i made 😊 im honored and this is why i love you guys, you respect love and appreciate your customers and viewers. I need to swing by one day and buy a new shirt cause ive lost a ton of weight and dont fit in the old one well now 😂
Special guest star... Shoutout to my main man, Bruce!🙌 Those spacers look nice, btw. I'm sure George will love all those brake upgrades. The first mod I did on my last car was Stoptech brakes (I believe they were 355mm, nearly 14"). Great video as always, guys. Y'all take care and have a good Monday, if that's even possible.😉
John...I work with p2r and let me know if u want to try our thermal spacers which takes the aluminum a longer time to heat up which allows for less heat soak during runs. Let me know if u have any interest in our product. It would help George on track days
I got one of these spacers for my 09 Si. 160k miles k&n intake and after installing the spacer it’s like night and day driving it. Throttle response is much better, the vtech changeover is smoother and it doesn’t bog after the shift at redline. No tune and it’s pulls smoother, it’s amazing compared to what it was. Best $ I’ve spent on this thing
That's crazy for the amount that they cost. I know on the 8th gen page, there was always a commotion cause no one knew the before/after on these spacers. Would definitely love to buy one of yalls, if yall still have them in stock
They do work, specifically on log style manifolds such B series by helping the closest cylinders, in this case 3 and 4, by making air distribution more equal. The slight bend in the intake helps a bit but paired with a spacer even better.
Love those Hawk HPS pads. I run them on my daily driver. They're an OK track pad but they get greasy for me after about 15 minutes at my local track and need a cool down. I use Hawk HT-10 for the track now.
Eric Dawson I would consider brake ducts. We use this combo with brake ducting on the S2000 and you’ll never heat them up. More heat in the pads translates to heat in the fluid and caliper too.
@@LHTPerformance I do have some ducting from the front valance pointed into the wheel well but for sure not directed at the rotor as good as it could be. I'm sure creating my own backing plates and attaching the ducting to them would solve the issue but my fabrication skills are somewhere between non-existent and backyard butchery. That said, I do really enjoy the HPS pads because they wear awesome, low to no noise, great cold bite, and in my situation can handle track duty just not as long as I'd like. Maybe some day I'll get another set and try to create some backing plates to attach some hose to from the valance and see if I get a better result. Cheers and thanks for the vids!
10/10 would highly recommend making more. You just made a video with proof. Bet these damn things will sell like hotcakes! Hell I'm interested! But, I need one with a 72mm bore. Hope you guys make some. Most of the ones now don't look like they are that thick. I'm not sure what the dimensions are of yours, but I'd say it would be a solid idea.
Very Nice content guys from an old 8th owner (miss it too) noce séries from Québec Canada ! Pretty much effectivement for a pièce of aluminium, that's surprise me for a cheap modification that's pretty effective worth it for sure ! Thanks for demonstrate that's very work for real !
Awesome to see you guys doing a & this gen was dying to see someone that know what they’re doing , do vlogs on these cars.. I love my 2008 four door Si
Hey George make sure you keep that thing waxed. I had an 08 Si and they are known for clear coat issues where it fades and peels off. I didn't have the issue since I kept up with my waxing but just a heads up. It was actually a factory recall.
AJ Imports, boost will fix everything. I don’t think we’ll build anymore b. We’ll let the Chinese rip it off and sell it for penny’s. Hence why I have 10 in a dusty box for over 10years. Lol.
Definitely loving the content. Keep it coming! I have stoptech rotors on my car and they have performed flawlessly. This past fall I overheated them severely and they didn't warp at all.
the smaller the engine that is n/a, the more beneficial bolt on mods are for them!! i got a 2015 1.8 with the r18 , and I put just a cai, with spacer, changed plugs, and it woke it up much more. this is even WITHOUT any exhaust work done or downpipe or anything. i cant wait to see what i can do with exhaust work, hondata tune and other stuff!
Nice! The old GSR had the same concept with its’ intake-manifold that changed runner length (remember their funny snail looking intake manifolds?) Also, it’s not uncommon to experiment and change runner-lengths for ITBs and even Carbs to tune and adjust power curves in race cars.
You guys do amazing work. I love the attention to detail, no corners cut with LHT. John i was wondering if your throttle body spacers fit the 9th gen Si's as well?
14:39 higher gain at higher rpm, with sacrifice at lower rpm. The spacer at lower rpm cause power lag (because the air fuel mixture now get longer way to reach the chamber), therefore the engine do what it can to compensate (tell the injector to spray more)
Fantastic and amazing results.... it appears there was absolutely no additional tuning, correct? just before and after? would agree with other comments... please do the same comparison on a s2000. I do wonder how much power can be attributed to the prior tuning, though.
Please test out the 70mm mdx or rl oem throttle body.. I need to see what it makes and if it fits your intake.. Is the civic with a oem RBC or a RRc intake..maybe because its mugen its the RRC
I am helping a friend do work on his stock k24 now and am looking into this also the cheapest i found is prl site its 169$ oem mdx 70mm so u can look into that
Did you consider adding a plastic/phenolic spacer to see if it would further reduce the air temps? Did you bypass the coolant hose to the throttle? Not sure if it is fully needed where you live.
Man, too bad I live in Indonesia. Wanna go to your shop. Just acquired FD2 but with K20Z2 150hp Any advice if I wanted to convert it to K20Z3's one beside RRC intake manifold?
so do you know if you add this type of mod to a 2012 civic si... will it cause the car to not pass emissions? here in the states i gotta go through emission testing like most states do... and it sucks cause stuff like exhaust... intake... i cant do that stuff because the car wont pass emissions... but yeah im curious if this little mod would do the same... will it cause you to not pass emissions? looking at it i dont see why it would not pass.... but i know even changing something as little as that can throw the car CPU into a loop and most the time you gotta go get it tuned and or use a flash pro to actually gain benefits.... just curious though if it will still pass emissions and also will you even gain HP just by installing or would you still need to get it tuned with a flash pro?
A back to back testing will be a more accurate test. The way the car is tie down to the dyno will change the figure. And the dyno loading ? 0.99 vs 1.01 ? Hmmm.. hp/torque graph is similar except the entire band is move up.. all the ups n dips is same.. seem to me its jus a dyno tweeking.. but hey.. who knows.. mayb honda didnt wan to make extra 5hp on the car w a simple 20mm spacing..
You may not believe it but in my 12v VR6 MKIII GLX Jetta I put an Intake Manifold Spacer on my Schrick VGI and it added around 5whp of power and kept the Schrick VGI much cooler. Yes some stuff sounds too good to be true and most of the time it is but sometimes you hit on a simple gem. What other mods do you have on The Civic Si? Individual mods are good but combining a CAI, TB, Header, and Exhaust often show more power than just one or 2 parts combined. Do you believe this to be true?
Matthew Mohri I remember trying one of these years ago and didn’t believe it. I removed it to confirm it actually worked. I’m usually skeptical as most things down work as advertised.
Alex K We haven’t personally tried it. It will however cost another spacer, one more gasket and longer bolts resulting in a lighter wallet for better handling. lol
I need this spacer for my si. How can I get this part? Thank you for taking off that front H. Nice clean car. Hopefully boost will be coming soon to match the looks.
I'm running a jackson supercharger on my 8th gen civic. I still have the coolant lines running through the throttle body. I'm going to be changing out the coolant soon. Been thinking about doing the bypass. Is there a big difference in intake temps when the bypass is done?
Essential Lites I don’t think it’s huge but anything is better than nothing especially with the Jackson supercharger! Look into merc racing for an after cooler for the supercharger

220 hp at the wheels without even touching the valve cover is awesome if you ask me. Loving the content all the way from Australia.
That is around 190-200hp at the wheels by European standard dynos then.
Kurosaki990Ichigo It is pretty good considering it still the complete exhaust system.
It does have a Mugen exhaust from the factory, right, but factory catalytic in place?

Can't wait to see what a nice 3" LHT titanium exhaust yields, it has to happen! I'm sure you can make one quiet too
Sime T I’d like to see this too
Because the exhaust is a genuine Mugen stainless exhaust and is very quiet, I don't think George wants to replace it. We'll see....;)

Should try this on NA s2k to see if they also increase the hp. If so that's another item you can sell in the LHT TLC package.

ASM/Toda produce a tapered spacer. It doesn't yield anything on it's own.

LHT does the best work, keep it up John
WOW , I Love this channel.....always great content and products hands down, I dont want one of these I need one of these!!! Keep up the great work
This makes me miss my Si
You guys do amazing work. I love the attention to detail, no corners cut with LHT. John i was wondering if your throttle body spacers fit the 9th gen Si's as well?
Great video. Another suggestion for brake pads is Akebono
biopqq I’ve heard but never tried
Would love to see something like this for an AP1 S2K!
Would the spacer make power with the k&n intake? Also it doesn’t loose peak power? I was always under the impression stock manifold was perfect
my k24 ep3 has honda accord cu2 320mm discs with 2pot calipers front only loved your video on intake/exhaust
Have Jorge P from MaxBore do the throttle body and see if there is more to be gained. Enjoying the series.
Wow that’s pretty cool, I hope you have one. I would like to purchase one but bills come first 🥴
14:39 higher gain at higher rpm, with sacrifice at lower rpm. The spacer at lower rpm cause power lag (because the air fuel mixture now get longer way to reach the chamber), therefore the engine do what it can to compensate (tell the injector to spray more)
Matius Teddy C. The idea of this test was not to adjust or compensate anything. Maybe a future episode will show more 🤔
That's impressive. I guess a little intake tract lengthening doesn't hurt. I wonder what adding a larger, tapered bore would do.
You can add a honda intake manifold insulated gasket and a j35 or j37 throttle body to it as well.
Fantastic and amazing results.... it appears there was absolutely no additional tuning, correct? just before and after? would agree with other comments... please do the same comparison on a s2000. I do wonder how much power can be attributed to the prior tuning, though.
I had these made back in 2008 for the Civic...Ive had 10 collecting dust since...I doubt I'll make more. Sorry.
Please test out the 70mm mdx or rl oem throttle body.. I need to see what it makes and if it fits your intake.. Is the civic with a oem RBC or a RRc intake..maybe because its mugen its the RRC
stefce trajkovski it is rbc and the intake comes with a larger silicon coupler for the larger tb. I’m working on a larger tb as we speak
I am helping a friend do work on his stock k24 now and am looking into this also the cheapest i found is prl site its 169$ oem mdx 70mm so u can look into that
Great numbers!!! Car should be fun to drive now
I'm loving it as well!
Interested to see what a stack of 2 would do if one is +4-5hp compared to stock.
Dudee!! Im loving it also that is sweet i want one!!
Can u try putting 2 spacers on top of each other?
Why stop at 2, do all 10! 😄
@@ayowser01 could be a good test and he would sell more lol
XDDDDDD
Good to know thanks guys.👍🏽👍🏽👍🏽💰
So will 2 spacers make 10 plus hp?
Always enjoying ur vids keep it up!
any chance y'all still making these spacers?
Keep it going! Love the car!
Nick Marlin thanks me too!!
Only reason it works is the engine wants more plenum volume. Effectively, that's what the spacer is doing, increasing plenum volume by roughly 57cc.
jdm92cb7 been along time seeing your name around, miss your old cb7 videos and your member ride thread.
thank you for sharing I'm inspired .
That infotainment screen on the Mugen Si is sick. Is there an install video of that?
For the throttle body water bypass you can use the S2000 heater plug instead of having a hose in the engine bay!
Fidel J id need 2 as there are 2 outlets. That’s why I just looped it.
@@georgefitzgerald5861 yeah just plug both of them! That's what I did on my 8th gen!
Fidel J I might but at the time I only had a hose
@@georgefitzgerald5861 do it! Itll clean up the bay@
You have any more spacers
It said SUMbody else..... hahaha
I laughed more than I should have....
J D lol. I have a dry sense of humor.
Love the Mugen Si!!!
Did you consider adding a plastic/phenolic spacer to see if it would further reduce the air temps? Did you bypass the coolant hose to the throttle? Not sure if it is fully needed where you live.
Yo also that touch screen on the dash is awesome looking! is that a upgrade that could be done to a 2012 civic si?
Great content
Nice …Where can I get one And how much please let me know
2020 Honda Civic sport 2.0L

Sold. I’ll take one please!
way late on this. would the k20a3 get any help from the spacer?
Any of these throttle body spacers for an 04 si ep3? Stock
So this illustrates with a couple bolt ons the engine likes a larger plenum 👍
Wonder what a ported manifold would do... 😉
SnyperTuned It May just be a future video 😉
PS can't believe you made that much HP with the spacer!!
Brandon K. Remember, the last 2 HP was from a cool down down. It’s called “The Money Run”. Lol.
Hi John, Hi George, Great to see you back on the Magen. How much for the spacer?
Shane Black Lord George is lovin it Hopefully MCDs does complain. Lol.
Man, too bad I live in Indonesia. Wanna go to your shop. Just acquired FD2 but with K20Z2 150hp
Any advice if I wanted to convert it to K20Z3's one beside RRC intake manifold?
Bruce! @ oca.....ups talk...
doesn't the correction factor of .99 vs 1.01 account for the difference?
What front lip does he have on there? It is not the same that came on my Mugen.
Any more of those throttle body spacers? I’d love one
Benny Hess I think we have 2 left. DM me on IG.
Paused at 1:10
Why don't you use StopTech brake fluid?
ABDULLAH_FARD M. We used and tested the fluid we use with great success. I’ve ran it in the Corvettes, the NSX and many track S2000.
so do you know if you add this type of mod to a 2012 civic si... will it cause the car to not pass emissions? here in the states i gotta go through emission testing like most states do... and it sucks cause stuff like exhaust... intake... i cant do that stuff because the car wont pass emissions... but yeah im curious if this little mod would do the same... will it cause you to not pass emissions? looking at it i dont see why it would not pass.... but i know even changing something as little as that can throw the car CPU into a loop and most the time you gotta go get it tuned and or use a flash pro to actually gain benefits.... just curious though if it will still pass emissions and also will you even gain HP just by installing or would you still need to get it tuned with a flash pro?
What’s the logic in that?? Also, is there any available for the b18c5?
Terry Low adds plenum volume and sorry none for b18c5
Would this fit on an FD2? If I recall correctly the Boomba for the K20Z fits the K20A.

What touchscreen are you guys using? Would love to get one for my Si
What will happen horsepower wise with two of those spacers stacked
Alex K We haven’t personally tried it. It will however cost another spacer, one more gasket and longer bolts resulting in a lighter wallet for better handling. lol
The world may never know
have a friend that use to run two spacers on carbureted V8 and said it maid more power according to his but Dino lol
This should have the same effect on my built b18c5 with a kraftwerks supercharger?
Any spacers left? And does the mm on the spacer need to match the exact size on the throttle body
Did you guys know if the 10th Gen Civic Si has a throttle body upgrade? I have the Skunk 2 intake manifold 70” with the stock throttle body “50.
I believe Skunk2 make one for it
Does spacers really work
Stainless steel brake lines read mixed reviews having them on a daily driven car.
Kenny_Fa5 There’s no negative reasons behind them all. We only use Goodridge lines.
I apologize if this question already been asked but what touch screen kit is that??????
