HPS Performance Black Reinforced Silicone Radiator + Heater Hose Kit Coolant for BMW 01-06 E46 M3 Left Hand Drive

The K&N 57-1543 Filtercharger Injection Performance Kit is an air intake system designed to replace your vehicle's restrictive factory air filter and housing. It smooths and straightens airflow, allowing your engine to inhale more air for increased power and acceleration. The kit includes a chrome-topped K&N high-flow air filter and a heat shield.

This intake system directs air through an aerodynamically engineered tube into the engine's throttle body, accommodating the factory air temperature sensor and providing a guaranteed power gain. The oversized cone-shaped air filter can last up to 100,000 miles before servicing is needed, depending on driving conditions. Installation is typically straightforward, often completed in 90 minutes or less using existing factory mounting points.
