The K&N Performance Airbox is designed to dramatically reduce air flow restriction as well as smooth and straighten air flow. Replacing the restrictive factory air filter and air box allows your engine to inhale more air than with the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. A fully enclosed injection molded air box connects to the factory air intake hose. The removable lid provides easy access to the filter when cleaning is required. This performance air box is relatively easy to install. The required tools are commonly available and it uses the previous air box space. These air box systems are built to last for the life of your vehicle and they're backed by K&N's No-Hassle Lifetime 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.Shipping Notes

Quick and easy part to install
Color: 40pcs
My wife accidentally hit a parking curb and popped the bumper cover of her car. The flexing caused some of the clips to break. The bumper sprang back, but the clips just fell out. Basically, they sacrificed themselves. These new clips fit perfectly and the bumper is ready for action. Keep some in your glovebox, you'll be glad you did.

Needed some of these since i was changing some stuff under my front bumper. They look and function the same as oem. And there are plenty to use as well. Would definetley pick up some of these as your current one will probably break as your taking them out.
