Brand New ACDelco PF52 Oil Filter with anti-drainback feature. This is the longer style oil filter that is commonly used to increase filter area and capacity on 1986-87 Vin 7 Turbo Regals and Grand Nationals.
These are "Dealer only - Made in USA" filters NOT AVAILABLE THROUGH THE AFTERMARKET!
Don't be fooled, you cannot buy a better oil filter! We have cut open various other well known name brand aftermarket oil filters and found some with only half the amount of filter surface area AND NO ANTI-DRAINBACK FEATURE!
These filters will ship in their original ACDelco box as shown.
