K&N are crappy filters. Go and get yourself a 6637 from NAPA or fleetfilters.com and use that. the ID is 4" on those and you need a 45* bend if i remember correctly.

Almost twice the cost of a 6637, but with a lifetime deal, that could be a winner.

Is this one of those "wash-and-wear" filters? Looks pretty decent and the size is similar to the 6637 as well.
