Description
The K&N Cold Air Intake System (KNN57S-2001) offers a significant performance boost for BMW 2, 3, and 4 Series models with the N20 2.0L L4 engine. This system features a high-flow, roto-molded intake tube and an enclosed airbox, designed to replace the restrictive factory airbox and filter for increased power and acceleration. The intake kit provides smoother, less restricted airflow to your engine, delivering an estimated gain of 8.5 horsepower at 5200 RPM. Constructed from high-density polyethylene, the intake pipe is both durable and optimized for efficient airflow, while the reusable cotton gauze air filter ensures long-lasting performance.
Engineered for easy installation, this K&N system requires no special tools or modifications and can generally be set up in under an hour. While not street-legal in California, this intake system complies with emissions and sound standards in other regions and is backed by K&N’s No-Hassle Lifetime Limited Warranty.
