One Day Deal IAG Performance BIG MAF Intake Polished 2002-2007 WRX / 2004-2007 STI

The IAG Big MAF Intake is a high-performance short ram intake designed to work with the OEM Subaru mass air-flow (MAF) sensor, offering a direct fit for 2002–2007 WRX and STI models. Engineered for maximum airflow, this intake routes air to the engine in the shortest, most direct path, improving throttle response and overall engine performance.

Constructed with a 3” diameter aluminum pipe, the Big MAF Intake enhances the maximum flow through the OEM MAF sensor. It features a K&N high-flow cone air filter, engineered to capture dirt while allowing a large volume of air to pass through, increasing horsepower and torque potential. The filter is washable and reusable, capable of lasting up to 100,000 miles before cleaning under normal highway driving, and is designed to last the life of your vehicle.

Installation is simple: secure the included hose clamps at each end of the silicone transition hose to attach the pipe to the intake manifold, and install the OEM MAF directly to the MAF port. Tuning is recommended after installation to optimize performance for the larger airflow diameter.
