Have any of you plumbed your intake thru the inner fender to bring cooler air into the air filter box ? There is a tube from the box to the inner fender but is has a big gap that allows hot under-hood in. I'm wondering if PVC would work and make it sort of a ram-air intake.

 

there is a thread on this in the how to section.

Hope this helps.
