All 2022+ Subaru WRX Intakes NEED A Tune... (Perrin vs AEM vs ETS) 

Been running Perrin on VB 22 for 55k miles, daily driver, no issues. I push it pretty hard quite often but nothing like track driving. If you're in a similar situation, you're fine.

I’ve had my mishimoto intake sitting in my closet for months until just recently 😁 told myself i wouldnt install it until I was ready to tune it and i’m now tuned for it by drunkmann tuning and i love it!

Great content. You cleared up my confusion on the choices on intakes. I’m now proceeding with an intake and Cobb tune .

Ohhh boy. The FA’s have full time closed loop fuel control, I don’t know what Subispeed is talking about.. They will adjust fuel delivery based on the output from the oxygen sensor compared to the target lambda value (that means AFR). There are limits to the amount of correction that can be applied however, they’re pretty large. Replacing the factory intake with an aftermarket intake will affect the accuracy of the MAF unless the manufacturer has specifically designed their intake to closely match the factory intake’s airflow over the MAF, which I’m guessing a lot of them have. This isn’t an EJ which uses open loop at high load/rom and had no ability to correct a lean or rich condition. People reporting “knock “ with certain intakes is purely confirmation bias, the FA’s have an extremely active knock control system with many variables. That being said, should you have the MAF table calibrated for an aftermarket intake? OF COURSE! You want to rely on the accuracy of the calibration and not the ability to correct. I’m not getting after you because your message is wrong it’s just inaccurate as fuck. Subispeed said several contradictory things in that video.

Im confused so manufactures make these products for example perrin with their air intake that says its "designed to run like the stock air intake" no tune needed and no risk of damage to engine. If this isnt true wouldnt perrin and/or other companies who make producs like that run the major risk of lawsuits because their products would be the direct cause of a engine failur?

i just pit intake to get the flutter i dont really care about power as of now😂

An intake will void my warranty so I just have an AEM drop in. I did notice a little more performance and intake sound.I'm assuming my car won't be running lean at higher rpms with just a drop in.

Good info✊🏿

Great video, Love it. From Plymouth, Mass, 22' WRX Orange.

It’s confusing because some say there Perrin intake is not running lean after 6000 miles and then others say to tune it

What I want to understand is if you add a intake and you get a tune are you then loosing your factory mpg under normal driving? Or are you gaining or staying the same because now you have more air and fuel? Maybe I answered my own question lol

I just had 2023 wrx and im planning to install perrin intake my wrx is stock and been driving this car with care. my max rpm is 3000 to 3500 and crossing aroung 2700 rpm. is it ok to install perrin intake?

Will removing the charcoal filter in the OEM air box cause as much leaning out as the two aftermarket air boxes which claim to not need a tune?

I think the only way to improve stock flow safely without a tune is with a drop in filter. I ordered cobbs a couple days ago and should be in soon

Is the mishimoto intake fine without an intake?

Thoughts on mishimotos no tune intake? 😅

I installed my ETS intake when it first launched and I lost an entire pound of boost,I still havent tuned it til this day but I emailed them about it and nothing was done.Even after I got a Lean Code and went to the dealer for the Diag.
