Product Description
Brand-new ACDelco PF52E Oil Filter with anti-drainback feature.
An ACDelco Specialty Ultraguard Oil Filter provides outstanding protection for demanding uses, such as racing, off-road, and heavy duty truck applications. With 98% multi-pass efficiency at 25-30 microns and burst-strength that is five times greater than normal engine oil operating pressures (as long as the normal engine oil operating pressure is not greater than 51 psi), the ACDelco Specialty Ultraguard Oil Filter is the clear choice when performance matters.
- Equipped with 98% multi-pass filtering efficiency at 25-30 microns for outstanding filtering capabilities
- Designed to withstand five times greater force than most engine operating pressures, after oil reaches operating temperatures, for a longer life
- Has a thermosetting adhesive seal to keep filtering media in place for dependable performance
This is an OEM GM "made in USA" longer style oil filter that is commonly used in place of the factory original size PF47 to increase filter area and slightly increase oil capacity for 1986-87 Vin 7 Turbo Regals and Grand Nationals.
Don't be fooled, you cannot buy a better oil filter! We have cut open various other well known, nam-brand aftermarket oil filters and found some with only half the amount of filter surface area AND NO ANTI-DRAINBACK FEATURE!
It's What's Inside That Counts
- Heavy duty shell material is tested to four (4) times the normal engine oil pressure
- Heavy threaded plate protects against pressure spikes eight times above normal operating pressure
- Spiral wound steel core tested to twice the OEM collapse requirement.
- Poppet style bypass valve with heat treated spring matching OEM pressure specifications.
