Review on 🚫 AEM 21-732C Cold Air Intake System (Not CARB Approved) by Richard Gross

Revainrating 5 out of 5

2015 Subaru WRX for filter

This is what my car needs. Should have bought it a few months ago. Easy installation and great sound! Allows me to shift much faster at higher revs. The bearing BOV is clearly audible. I'm still trying to see if I can save some more fuel. Unfortunately it won't come to that, because now I want to step on the gas as often as possible. You can clearly hear the air leak and I feel like the car has a little more torque than before. Highly recommended to anyone undecided. I run it without melody. I heard from my Subaru mechanic that these cars come in for repairs because people blow out one of the pistons because of the Cobb tune. It's just perfect the way it is for me!

Pros
  • Perfect for outdoor activities
Cons
  • Not bad
