i installed a SLP airbox lid today....

if you run a k&n filter check the seal at the back of the lid. my slp didnt seal very well. the k&n filter is about 1/8 " shorter then stock. when i went to clean my filter i found that it wasnt dirty at all. and there was a lot of $hit stuck the the mass air screen. i fixed the problem with some 1/4" x 1/4" fome tape from the hardware store. checked it after 1000 miles and there is nothin on the mass air.
