Brand: K&N Engineering
K&N Performance Gold oil filters flow up to 15 gallons per minute and are completely unaffected by racing gasoline, methanol or nitromethane fuels. A 1 inch hex nut on the end allows easy removal. The nut is even predrilled for easy safety wiring. Anti-drainback valve eliminates "dry starts" by preventing oil from flowing back into the crankcase during engine shutdown.
This filter has 13/16-16 threads and a large diameter O-ring to fit Big-Block Chevrolet engines. 3.7" OD, 5.7" long. Replaces Fram PH13 / PH5 and WIX 51060 / 51061.
