The K&N 57S-4902 Performance Airbox replaces the restrictive factory air filter and air box. K&N performance air boxes are designed to dramatically reduce air flow restriction as well as smooth and straighten air flow. This allows your 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 57S-4902 Performance Airbox comes with a chrome-topped conical K&N high-flow air filter and a fully enclosed injection molded air box with an intake pipe that connects up to the factory air intake hose. The air box has a removable lid for easy access to the filter when cleaning is required. The air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This performance air box is relatively easy to install into the previous air box space with commonly available tools. K&N builds these air box systems to last for the life of your vehicle and they are backed by K&N's Million Mile Limited Warranty. Some K&N 57S Series Performance Airboxes are compliant with the latest TUV emissions and sound regulations. Check the K&N catalog or website for vehicle applications and specific TUV status for each vehicle and air intake.

K&N 57S-4902 Performance Air Intake System Product Reviews

Wednesday, August 23, 2017 - Part 57S-4902
Love it! You can use it without the heat shield if you want more intake noise.

Great product, fits just as easy as the original. Noticeable sharper response from the car and doesn't make it sound silly. Worth every penny.
