K&N Replacement Air Filter
  • Designed to Increase Power

Burke Schmidt, Salem, Oregon
I purchased this filter as it is designed to breath easier, be cleaned and last for many more miles than I'll drive. The reputation of the company is good and that made the choice easy. I have a class B motorhome which uses a gasoline V8 engine, and any modification like this can help make it more even a slight bit more efficient. It installs easily, once you get to the engine.
