I run with my airbox lid off on my Kawasaki Teryx. The
performance is good, but the filter gets dirty so quick, the benefits aren't
worth the hassle of a dirty filter after just a short bit of riding in dusty
conditions.
I had used an airbox cover from EHS Racing on a few of my
ATVs in the past, and was very happy with the results. I checked the EHS
Racing website, and to my dismay, there was nothing listed for the Kawasaki
Teryx. Not one to give up that easily, I picked up the phone and
talked to Eric at EHS Racing.
Eric didn't have anything made yet, but said he would get
right on it. A week later, the airbox cover was shipped.
The cover takes a little bit of work to cut out the center
section of the lid and drill a few holes, but it took me about 1/2 an hour.


Mark the area to be cut. I used a jig saw. Cut
does not need to be perfect (obviously).
I did grind down a few of the vertical pieces on the inside
so the nuts would sit flush.
Bolt it all up and you are done!
