Before getting your post, I was modifiying a 4-inch Rubber pipe Cap from Home Depot ($3.88) to fit my 4-inch 'closeout' Power Adder air filter, so if that doesn't work, I'll check out the ebay adapters you mentioned.

I'm wondering why the K&N designers didn't suggest something to pull cool air from the outside instead of sucking in hot engine compartment air when using their FIPK (57-9005) kits? It only makes sense to me, but I'll test out my invention and "engineer" something like you mentioned that would help block the low restriction air filter from seeing hot engine compartment air.

Thanks,

Mitchell
