Easy to see the difference that this filter makes. I use K&N filters on all of my vehicles. It's the only way to go if you love your machine.

I like K&N filters because of the ease of cleaning. There is a lot of dust and dirt in the air in west Texas. It is very hard on air filters. I would not use anything but K&N.
