That charcoal filter is actually a EPA thing. It stops fumes from coming out of the engine and into the atmosphere after you turn your car off. Other than that it does nothing. So nothing big really. I would imagine it would get quite restrictive after many miles were put on the car.
@@Vanithoth I bought an aftermarket air intake box modeled after the OEM one cause I couldn't find a used one anywhere, I really hope that mesh isn't important in the long run cause it didn't have one when i unboxed it.
You can see more details in my “DIY air intake” video, but once you have a filter on the crank case side, you can cap the side on the intake or delete it like I did with a straight pipe
No, but you can drill a smaller circular hole very easily, or if you just don’t want to do all this and have some money you can buy the f-sport lower air box, it’s about $70-$90 depending on where it’s for sale and it does the exact same thing, the whole f-sport intake doesn’t make a big difference overall as I have seen, but it’s just up to if you want to go all the way to get it, I’m just buying the lower air box for induction noise
So I personally would not make the hole in the intake..heat soak..I did remove the mesh and it make a big difference in performance and miles per gallon if you drive it slow. The car has a good intake airflow already...not restricted but aperently the mesh was restrictive...I have a tune and boltons on my car. Removing the mesh and putting a f sport filter took it to a perfect level...thanks for the content I hope everyone removes the mesh.
are you sure we don't need the mesh? I bought an aftermarket air intake lid cause I couldn't find any OEM ones for sale. it did not come with that EPA mesh thing, I really hope it doesn't ruin the car in the long run
@@mazpr2025 i couldnt find a used oem one anywhere so i ended up buying an aftermarket air intake lid and an oem f sport lower box and tube. was nervous though cause the aftermarket upper lid didnt have that mesh
Dodgy? This is exactly the same as the OEM F sport air box. I guess Lexus engineers don't know what they're doing allowing hot air to enter the airbox by leaving that big old hole there😂. You bloody armchair engineers always trying to talk shit 😂
Definitely 'sounds' faster, lol. I like it! Will be doing on both my Lexus and Pathfinder.
What tool did you use to cut the big hole?

you think it's really that bad in the long run with no mesh?
@@leocastrillo759 It would be better to remove the mesh than to have it on there. Removing it will do nothing but potentially increase air flow.

@@leocastrillo759 Unless you live in California, you won't need it.
Ur 350 is clean. I cut out the upper mesh filter and put a k and n. Guys is the extra hole in the lower box going to help?
Can I ask why all the little holes then the big hole? Not just cut it out at once?
Instead of cutting the whole thing its easier to drill small holes and less cutting.
@@tadas8808 true that
the little clip to remove my maf sensor snapped off because it was so brittle. How do i remove the wiring harness from the sensor now?
Will doing this void extended warranty?
Quick quest the lines of the intake do those matter I know one of them you put the little filter but does the upper line matter

Should I disconnect my battery before this, or will it be ok if I don’t turn the ignition on while doing this?
I did not unhook my battery during this mod!
@@pigeon853 ok, thanks for the quick reply 👍🏻
just did this waiting for my f sport intake tube in the mail haha sounds great thanks man
Sounds dope I will try this
What are the sizes of those silicone elbows from the throttle body and the airbox side? And where did you buy them?
Check out my other video on how to make a diy Fsport intake! The sizes are listed there!
I did the air box mod and my gas mileage dropped from 22-23 to 19-20. Definitely don't recommend this unless you prefer sound over gas mileage
Im thinking about doing this at my rav4 but im considering about the drawbacks that ive read on some forums like hot air sucking etc..
And the drop in gas mileage
About to do this to my GS350 tmw, any issues bro?
Nope! I dont regret anything!
Jesus. Night and Day difference. I'm doing this ASAP
Do you know the exact dimensions of the extra hole on F-Sport lower intake air box?
I do not
No, but you can drill a smaller circular hole very easily, or if you just don’t want to do all this and have some money you can buy the f-sport lower air box, it’s about $70-$90 depending on where it’s for sale and it does the exact same thing, the whole f-sport intake doesn’t make a big difference overall as I have seen, but it’s just up to if you want to go all the way to get it, I’m just buying the lower air box for induction noise
Just did this airbox mod and my muffler delete drowns out the sound of the intake lol
do i need a third party air intake tube?
Not necessary
Does the lower airbox fit on a gs350? It looks the same
GS and RC should be the same, IS has different clips for the top and lower boxes.
will it do just fine if i don't break off those little pieces inside?
Yes!
Nice bru. Ill do it to my car too.
You feel more power?
Not really any more power, but it sounds waaayy better! You wont regret it
Perfect way to mess up a proper designed air box lol
They come like this on the F sport from Lexus lol.
you missed the part weird lexus sell you thiss part smh 🤦♂🤦♂
What intake tube is that ?
You can get a f sport tube or I recommend the rr racing carbon fiber intake tube it’s $139 but it’s on sale rn for $109
@@noahcortes9991 yea i ended up getting the rr racing intake

@@leocastrillo759 It will not
*there is another metal mesh on the TB to catch anything that may pass through.
The ISF has the hole from factory, a V8 5L, way more heat. I do not see where the issue is on smaller displacement.

Did this mod "throw" a code on your dash?.
No!
But in your video stock on light and then you did mod and you had a light on
@@thomb1124 it just the light to check your oil or in his case looks like he just needs air in the tire I don’t see a check engine light at all
I love lowering the value of my vehicle and paying to repair or replace parts. Alls I gotta say is Phuck! California!
then buy the lower box directly from lexus and it still pass emission yes even in california smh 🤦♂🤦♂
Dear god. What a dodgy hack and way to allow hot air to enter the airbox now
Identical to the OEM F sport air box. This actually decreases the IAT if you want to go check the data yourself. I have.

you dont know what you are talking about look out for the fsport intake oem part with a big hole just like he did

Might kind of work but that cut is awful...Butchered it
