Great filter with a great price
Installed this great K&N air filter in less than five minutes! Fits well in the air box. Comes with a tube of sealant lube which the amount of lube in the tube will last as long as the filter! It made a small difference in my throttle response and seems to have helped the popping when letting off the throttle. This replaced my original air filter that crumbled as I was removing it. Can't beat the price <$40!

Way better than the stock
It works great, make sure your motorcycle have the correct jet on the carburetor.

Buy it
It’s K&N, what’s not to love! This pairs well with the Pro Seal for mess free maintenance and eliminating need for greasing contact surface to create a seal

Awesome !
You already know how K&N is. One of the very best companies to produce top quality filters. Anyways the only reason I knocked off a star was because it fits loose on my 2014 DRZ400SM. And the glue grease thing that comes with it doesn't really work since it fits loose but thankfully the box has that metal strap that goes over to strap it down. I noticed a way better air flow and if you have a after market pipe it makes it sound a bit deeper too. Also when you add this filter don't forget to do the 3x3 air box mod. It's easy look it up on YouTube. But over all great quality it's jut loose.
