This intake replaces the restrictive factory intake plumbing and air filter with aperformance-oriented system that increases airflow, improves throttle response, and enhances the induction soundwithout compromising drivability.

This intake features a black powder-coated aluminum intake tube that resists heat soak and corrosion, along with ahigh-flow oiled performance filter designed to maximize surface area for airflow and filtration. Wire-reinforcedsilicone couplers provide improved durability and a reliable seal under all driving conditions. The CNC-machinedMAF adapter ensures accurate airflow readings for the stock mass airflow sensor, contributing to smooth throttleresponse across the powerband.

Installation is straightforward, requiring only basic hand tools and the included clamps and hardware for a completebolt-on fit. Fitment is confirmed for 1999 through 2006 BMW 3 Series E46 models with naturally aspirated 2.5 L and2.8 L engines. This intake is not designed for turbocharged or supercharged variants.
