I was hoping this week would be about intakes 😅 Very good info and confirms I'm on the right track. Been thinking of making a short ram intake + stock air box combo.
Can't wait for the next vid cuz thats where I'm at. Was gonna wrap my intake with some reflective heat tape, but explaining something so gaudy to the smog guy might make him wanna fail me.
Awesome video and great info for us. My pockets wish I did learn about this intake info before buying the BMS stage 2 but kinda happy I did. Excited to hear about the downpipe as that's my next mod idea for 4th gen turbo. Can't wait for more info on the big turbo. I'm focused on trying to increase 1/4 mile time and still keep car as a daily driver. Happy if I can hit mid 12s. Hoping to with big turbo and running e30vin the future.
Owner of a Sri and heat shield. What I did was make a lid for the heat shield out of ABS plastic and I secured it to the shield with spring-loaded latches. I then covered the lid & corksport heat shield with DEI Form-a-Barrier, which is a moldable heat shield. Now, instead of having the top of the air box open to suck in all the hot air that has risen to the top of the engine bay, the filter is encouraged to intake cooler air from the wheel well since only the side, bottom, and rear of the intake box are exposed. I think hood vents would help even further.
@SirTublington I've thought of that, but isn't the filter too loose, dangling and moving without anything attaching it? Or does it rest enough on the bottom box to hold it ?
What are you thoughts on the 3rd gen AEM short ram? I'd imagine if it was hot enough heat soak could still happen in the engine bay at a standstill but do you think how the design utilizing the oem snorkel to feed air makes a difference?
@muckeyn it doesn't do much. The best aftermarket intake for 3rd gen is Kodostyle & Autoexe. Personally, I'd do the AFE drop-in & the Autoexe Silicone hose
IAT is definitely very important. Since I have Torque Pro I can monitor IAT, among other things. Comparing the stock air box to the CS SRI, actual IAT was not going more then 10 C over the air temp when standing still, like 30 C. With the SRI it goes up like 40 C above air temp, overring around 60 C when standing still, 55 to 65 C, that's a big difference. It does go down pretty quick when moving though, but starting from a dig you're loosing some power until 2nd or 3rd gear. With that IAT compensation table, we clearly see how the ECU protect the engine. I got the SRI because I'm waiting on there turbo "cold air box", love the sounds but can see how it can loose some power in lower gears. BTW from the readings, we have to clarify where the IAT sensor is exactly, because there's also an Air Temp sensor that reads different then even the ambiant temp sensor in the dash. I think there might be a sensor in the charge pipe just before the throttle body(there is 2 sensors there, 1 temp and 1 pressure I'm pretty sure on how they look) and probably one inside the intake manifold after the water to air intercooler.
Yes, 4th gen turbo has more than 1, NA 3rd & 4th gen don't, so that's why I was referring to the 3rd gen turbo kit not monitoring the post charger temperatures
@@supermazda3 yeah the 3rd gen really wasn't thought by Mazda to have a turbo, so less "protection" for it. From what I see in Torque Pro when I was riding earlier, the IAT might be the temp sensor in the MAF, and Air Temp would be the temp in the intake manifold after the intercooler just before it goes in the engine. Outside temp was 23 C and the Air Temp was staying pretty much steady at 20 C standing still or moving. Food for thoughts, I will look into that.
Hey Justin, I just ordered a silicon hose from milkstore for a 3rd gen 2.5 NA. Is it the same length as a 4rd gen ? 6.5 inches/165 mm? Or does 5.5 inches will fit ? Thanks
I wonder if removing th carbon filter would in any way damage the filter due to what not having it will allow to pass through to the engine air filter from the intake.
Just removed my afe takeda intake and reinstalled factory air box w stock filter and no charcoal . Ordered a mikstore “auto exe “ hose hopefully it is long enough!
Another thing to add, the Corksport short ram intake MAF housing diameter is smaller than the stock air box MAF housing diameter. At least for the 4th gen. That alone is a downgrade
Hi justin sorry to bother, I just installed the bms intake on the car, turned it on and drove it around the block to make sure it was fine, is it normal for the car to be a bit sluggish at first after intake install? Thank you!
@@supermazda3 I did, it was disconnected throughout the entire process, guess ill check everything tomorrow but it all seamed well connected, oh boy, lol thanks dude
@nikolashauzeur7310 ah, well, that makes sense. Your car is just going through the learning phase again. It should be back to normal in a few hundred miles
@nikolashauzeur7310 I'm not sure who you are, but hopefully, if it's one of my customers, you definitely don't have the proper tune for a dyno since i haven't released the updated
Hey man I have a question. Just got a 2021 Mazda 3 Hatch FWD in the highest trim (In Canada it’s called GT). I’m worried about the longevity of the cylinder deactivation, is there any way to turn the feature off? This would be a huge help, even making a video about it would be amazing
There hasn’t been any issues with longevity a few of my Supercharged customers including myself have cylinder deactivation. I can smooth other the cylinder deactivation but turning it completely off the car loses practical drivability in a certain range. Not worth the trade off
I wrapped my stage 2 intake in gold heat reflective tape, specifically just the 1st half of the piping that connects into the engine right before the BMS "heat shield". Figured it would help heat soak. Wondering if that affects temps at all. Also, do you have any thoughts on turbo blankets? Would that also help with temps in the engine bay?
Turbo blanket also helps limiting radiating heat from the turbo, on a 3 the turbo is pretty small and cramped back there, could be a PITA to install one but could be worth looking into it. I have one on my supra and it helped under hood temps and the charge pipe going right over the turbo, which I've wrapped in gold reflective tape too. I would look into ceramic coating of an aftermarket downpipe before installing it, would also help on the temps.
@@supermazda3 I had the K&N SRI before I installed, and for a bit after but as it was getting hotter I could tell it was effecting it so I just thru the stock back in there and smooth as ever, however no more whine noises :(
@@supermazda3 3rd Gen, it had the heatshield that came with it installed yes. It had some rough shifting with the SRI installed also once it started hitting 100f
just copped a corksport sri for my NA 3, I live in Canada and the hottest it gets is roughly 90 fareheight, do you think buying he cold air box is worth it or not?
@supermazda3 I still refuse to remove it bc of the turbo noise, but hoping you'll say the loss isn't too extreme on the turbo 3? 🥲 Need to hit you up soon about tuning too, I'm itching to void the 95k miles of warranty I've got left lol
As Justin mentions in the video check your plug gaps I have had 3 different ngk plug sets all had the wrong gap out of the box
Seriously, thank you for these videos. They’ve been a huge help and I’ve learned so much. Can’t wait to get your tune on my car!
Not everyone appreciates it, but I'm glad you do
Salute Justin! This was the exact data i was searching for. You came with the receipts and everything!
No problem
Seriously helpful video! I will look for u to tune my Mazda3 2.0na when i get all the things prepared!
@@DerickHo sounds good!

For the ND you can also buy a JBR silicone hose. Edit: i had written this before you commented it on the video.
Glad to hear that the stage 2 from BMS was worth the investment. Thanks for all the information. 🙏🏽

It's definitely possible, and you don't even need e30 to do it
i have a completely stock for now 2.5 skyactive na and you can feel it pull power on a hot day even in stock form
@@thetechlibrarian yes sir they are very sensitive to temperature
Regarding corksports SRI, would it help if I bought the heat box cover and some DIY airflow directory to the intake?
Absolutely
I was wondering this also, I have the heat shield with factory air ram hooked up to it

Have my CS SRI on my turbo model. I kept the bottom of the stock air box in and lay the intake filter right ontop to help dorect air flow
Definitely a great idea, I did the same
@SirTublington I've thought of that, but isn't the filter too loose, dangling and moving without anything attaching it? Or does it rest enough on the bottom box to hold it ?
@redboy81 with the Autoexe it isn't on mine
@@supermazda3 ok, but is it the same on the turbo ?
@redboy81 I don't have a CS intake, so I can't speak on its rigidity. Many of the other short ram pipes are metal like AEM/K&N
What are you thoughts on the 3rd gen AEM short ram? I'd imagine if it was hot enough heat soak could still happen in the engine bay at a standstill but do you think how the design utilizing the oem snorkel to feed air makes a difference?

I wonder if removing th carbon filter would in any way damage the filter due to what not having it will allow to pass through to the engine air filter from the intake.
It doesn't, it's mainly for gas vapor
What’s the name of the better downpipe that you mentioned in the video for the 4th gen turbos?
LP CustomFab
Just removed my afe takeda intake and reinstalled factory air box w stock filter and no charcoal . Ordered a mikstore “auto exe “ hose hopefully it is long enough!
You will see an improvement in fuel economy
@@supermazda3 yes I already have noticed better mpg . The car seems to run much smoother as well .
@@stefanst-onge7378 you can put those plugs back in 😉
@@supermazda3yes I definitely will re install properly gapped GTR plugs
what is the gap supposed to be??
Air temps make huge differences hense why old school builds would have IAF installs running to a closed box around the short ram intakes.
Or they would throw a block of dry ice in their intakes for races and events then pull it after to fry overnight.
Another thing to add, the Corksport short ram intake MAF housing diameter is smaller than the stock air box MAF housing diameter. At least for the 4th gen. That alone is a downgrade
That'll make the car run slightly rich until the car adjusts

You're better off just freeing up the exhaust flow as much as possible to reduce Exhaust Gas Temperature
Turbo blanket also helps limiting radiating heat from the turbo, on a 3 the turbo is pretty small and cramped back there, could be a PITA to install one but could be worth looking into it.
I have one on my supra and it helped under hood temps and the charge pipe going right over the turbo, which I've wrapped in gold reflective tape too.

I installed the supercharger and now that here in Arizona its starting to get pretty high I installed the stock airbox there is a big positive change
