Hi,
I spend the extra buck,12 to be exact,and run the K&N HP2001.
??? I just bought a AC DELCO Oil Filter forthe first time at autozone and it said I needed a PF47? Are you guys using biggie filters or something?
PF 47 is stock shorty. PF 52 is same diameter, just longer.
Biggie filter is an entirely different number
Nice so it is PF52 the longest you can go without the Biggie kit from RJC.
I got news for you most of the AC Delco filters don't even have the anti drain back anymore! I stopped using AC Delco when I would start the car and it was making noise.
the cheapest filter is going on.
