I am looking at retaining my stock air bok lid but modyfying it would the EHS lid be a good answer? Will I pick up any power? And should I run it with a k&n filter?

 

I've got one.. although I have yet to install it. I talked to the guys at EHS and they said jet it to run with the Air Box lid off and it should be ok.

 

I run EHS lids on all my quads. They have saved me tons of time in cleaning airboxes. I can run the same jetting with my EHS lid on or no lid at all. Between the snorkel and the lid modification, it breathes the same as no lid at all. Try one, you won't be disappointed.
