Excellent filter. I always replace original filter with K&N filter at first change for new vehicle. Less garbage, less money over time, and a better filter.

One reason I bought the Green Filter over the K&N is because the Green Filter is made in the USA. The other reason, I was curious about the sound factor. It sounds really cool when you mash the throttle, but isn't obnoxious. It can be annoying at times, but is mostly not even noticable
