AMR BMI (Big MAF) Cold Air Intake for 08-12 WRX & STi

The AMR BMI Cold Air Intake System for the 08-12 WRX & STi is hand built in-house to ensure fitment and quality. The AMR BMI intake comes coated in a wrinkle red finish to match the STi intake manifold.

The AMR big MAF cold air intake system features a 76mm pipe diameter, making it one of the largest available on the market. Taking advantage of the 08+ WRX/STI facelift, AMR has designed this cold air intake system to provide fresh, cool air to the intake air filter, rather than heated air from the engine. Please note that this intake requires the AMR big MAF AccessPORT reflash or custom tuning to ensure proper air/fuel ratios and performance gains.

MADE IN THE USA! All AMR parts are made in house!
