Review on πŸ”₯ AEM (21-725C) Charcoal Cold Air Intake System: Boost Performance & Efficiency by Jose Baldwin

Revainrating 4 out of 5

An affordable, car-friendly screw with a noticeable increase in performance, although it's only a stepping stone! A+

[Bought For 2011 Scion TC] Perfect Fit! Increased gas mileage (average +4 mpg), slightly more aggressive starting and acceleration. You will definitely notice better throttle response as the car comes standard with a "sport tuned exhaust" and the engine bay looks nicer. But to really unlock the potential, you'll need a new exhaust system (no headers needed). Rumor has it that the Tsudo exhaust system + this AEM CAI is amazing.

Pros
  • Confident
Cons
  • Out Of Style
