For header clearance on my Swinger on the filter side, I jut went to the short version of the OE filter. At the time it looked like the 90° adapter would just move the full size filter into another zero clearance situation :wtf:
I have no room for filter in my Fargo, used a 51348 wix. Its k-car size filter. I change oil often enough so its no big deal. Smaller diameter but still fits. Considering my Avalanche uses a similar size, im not the least bit concerned.
