Default 2002 WRX AEM Cold Air Intake Tune

Just bought a 2002 WRX wagon and the guy gave me a brand new AEM Cold Air intake. This is a completely new realm for me (the 2.0L) so forgive my innocence

The car is completely stock at the moment, but I have a cat back exhaust coming in this week.

I really don't want to get another Accessport, (I have one for my 2008 STi) because I don't plan to do a downpipe and go stage 2.

BLUF.. do I need to get a tune for the CAI and Catback? I would like to use the intake, but I can definitely do without and try to sell it.

If possible, I am looking for someone who is willing to write me up a tune to flash on my WRX. I have ecuflash and a Tatrix cable but not much experience with tuning.

I would like to get the most out of my stock turbo (SAFELY) and enjoy the car.

Thank you in advance!

Hey there! It is recommended that you do get a tune for your CAI. Without a tune you're still running on stock MAF values which differ from what is actually going on with your CAI. So, in order to hit your target AFRs and ensure that you're not running lean, a tune is highly recommended to rescale your MAF. I will send you a pm with more information!

From what I've seen with the GD AEM intake, you'll need to increase the MAF scaling by about 12-15% up top.

my opinion (and alot of other ej2.0l guys) is stay with stock airbox and filter setup unless you are going to a huge turbo. the stock one filters good, already uses cold outside air, is quiet, is already scaled perfect, flows plenty of air for stage 1-2-3.
