Product Description
The K&N 57-1000 Air Intake fits some BMW 323Ci, BMW 323iS, BMW 325Ci, BMW 325i, BMW 325iS, BMW 328Ci, BMW 328i, BMW 328ic, BMW 328iS, and BMW M3 models. See vehicle applications below for details.
The K&N 57-1000 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some BMW models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your BMW’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-1000 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The air intake assembly accommodates the factory mass air sensor, speed control and throttle body thermostat (on certain vehicles). The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points. The tools needed are a couple of screwdrivers, a socket set and one 10 millimeter wrench.
