Using your K&N Performance Airbox is easy. First, make sure your engine is turned off. Then, follow the included instructions to install it in the previous air box space. You'll only need common tools for this job. Once installed, your engine will start getting more air, which means better power and acceleration. When it comes to maintenance, regularly check the air filter. If it looks dirty, remove the lid of the air box. You can clean the filter with a K&N filter cleaning kit. Just follow the directions on the kit. It's important to note that some models need to meet TUV emissions and sound regulations. Always check the K&N catalog or website for your specific vehicle's TUV status. Keep your air box dry and away from any corrosive substances to make it last as long as possible.
