Does anyone have pictures of what their Napa 6637 custom install looks like? I've run the K&N filter for more than a decade and within a week it always says a have 65% restriction at the vacuum sensor. I installed a new paper element instead from Federated and within 3 days it started reading 50% restriction. I think this diesel needs more air but the 6637 is larger than the airbox. I was hoping to leave the base of the airbox installed the the filter could set in their but get 360 degrees of air access.
