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 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.Installation Instructions

Nice piece but not for BMW motorcycles
Solid filter wrench. My bad for not checking the fit. Way too big for BMW filter 11 00 1 341 616 on my motorcycle. Turns out I had one that fits anyway. How dumb was that? I didn't get to try it on anything but four stars for appearing to be a good solid tool.

It fit
BMW X1 2015. No problems at all. You won’t need any other cup unless you have more style euros.
