I'd return the K&N to the store without opening it. They're nothing but junk and a good way to let in too much dust. Here's a hint: If you can see between individual strands of the filter material, it's no good.

Here's a good thread on the subject.

A good quality paper filter does a much better job, is cheaper, and all that a modern fuel injected engine needs. A carburated gasser might like the K&N, but when there is a computer monitoring the air/fuel ratio several times a second, there's no need for the K&N.
