AMR Big MAF Cold Air Intake 2002-07 WRX / STI

The AMR big MAF cold air intake system features a 74mm pipe diameter, making it one of the largest available on the market. 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 bay. You can also be assured of proper fitment with your AMR FMIC! A K&N rechargeable performance filter ensures maximum flow and horsepower gains and the wrinkle red aluminum piping will look good for a long time. Please note that this intake requires the AMR big MAF AccessPORT reflash (available separately below) or custom tuning to ensure proper air/fuel ratios and performance gains.

Note: The Cobb AccessPORT map or a custom tune is required to run this intake system. The Cobb reflash is available separately below. AMR's map will scale fueling to work correctly with the Big MAF.
