🔍 K&N Engine Air Filter for SUZUKI/KAWASAKI 2000-2019: High Performance, Premium Quality, Powersport Filter - SU-4000, Black Review

Inadequate design that does not ensure the tightness of the air chamber. It leaves a 1/8 inch gap in some places because it doesn't use gaskets or gaskets. And the "gasket grease" is utterly useless because it moves so easily, and that after bending the metal of the stem. holder to be firmer. I would send it back in a heartbeat if I hadn't already thrown the box away. Get a foam filter instead.

This great K&N Air Filter installs in less than five minutes! Fits well in the air chamber. Supplied with a tube of sealant, the amount in the tube is enough for the life of the filter! This changed my reaction to the gas a bit and seemed to help get rid of pops when releasing the gas. This replaced my original air filter which fell apart when I removed it. The price of <$40 can't be beat!

This filter allows my bike to breathe a little better. It also helped my bike with the backflash problem. Sometimes it still backfires, but much less and much less severely. Also helps with the initial throttle click feel. The quality of this item is amazing. Really well built, solid and durable. Overall 10/10 I would buy again (if I ever need it but this thing actually lasts longer than my bike).
