i wanted to put some kind of aftermarket air filter on my 450r and i was wondering if the ehs system is a good one or if anyone else has some better ideas for me. i want some power gain along with the insurance that my motor is safe.

 

try one of these.

I'm using the K & N but will probaly switch to the foam. I have had no problems with the k & n. I also cut out my airbox lid to match the 04-05 HRC lid. I then slid it down an old pair of pantie hose. It works great. It acts like a pre pre filter. Remember you must rejet if you add more air. They are jeted lean from the factory. check out 450.org and 450rheadquaters.com for more info.

 

thanks alot someone that may actually know what there talking about.

 

I run the EHS lid with the ProDesign foam (made by UNI) filter and adapter.

 

how good do they work and do they keep it clean
