I just installed some 1.75 Rush Slip Ons and a PCIII with a K&N air filter. Sounds great now. Question is when I installed the K&N the cover went over the filter with no backing plate for it. Is this right? This means I cant use the seal that used to go between the back plate and the cover. This means the cover only seals the center part of the filter and the rest is open? This didn't seem right but I don't see any other way of doing it. Please explain. Thanks.

There has to be a backing plate otherwise there would be nothing to mount the filter to. What did you do? Just hang it on the throttle body?
Just kidding
The seal is not needed with the k&n 3909 filter seals against back plate and cover.
i agree there should have been a small backing plate that came with it. it's a nice set up and they work good or i should say as good as alot of them out there on the market.and most of them use some type of k&n filter.
