PF454 Oil Filter Cross Reference: AC Delco PF454 and PH454 Equivalents

The ACDelco PF454 is a short 13/16-16 spin-on with an anti-drainback valve, GM number 25324052, for 1999-on Chevrolet and GMC trucks and vans with the 7.4L and 8.1L V8. Its equivalents are FRAM PH8873, WIX 57099, Purolator L15313, K&N HP-1011, Baldwin B1438, NAPA Gold 7099 and Bosch 3322.

PF454 Equivalents by Brand

These are the parts each manufacturer's lookup returns for the PF454. Every row was checked against WIX's lookup, and the ones Baldwin and K&N also publish are marked.

The PH454 that turns up in searches is Champ Labs' number, also sold under the Luber-finer, Warner and Parts Plus names. GM's own number for the PF454 is 25324052, which WIX and Baldwin both cross to the parts above, and Baldwin also accepts GM 89060467.

A Purolator "PF 454" Is a Fuel Filter

WIX's lookup for PF454 returns a third row that has nothing to do with oil: a Purolator part numbered "PF 454", crossed to WIX 33112. WIX lists the 33112 as a 142 mm fuel cartridge for Deutz, Mercedes and Volvo equipment, and Baldwin sends the same Purolator number to its F950-F fuel filter.

So search the number with the brand attached. "ACDelco PF454" is the oil filter; a bare "PF454" can land you on a fuel element for industrial equipment.

PF454 Size and Specs, by Brand

ACDelco's own site publishes no spec sheet for the PF454 that I could find. The equivalents' spec pages agree on the thread, gasket and anti-drainback valve, but not on the height.

FRAM's PH8873 page gives a 3.050 in can with a 3.140 in gasket ID and states no bypass valve. WIX rates the 57099 at 3.306 in, 245 psi burst and 21 micron nominal, with a 3.444 in by 3.100 in gasket, so the four cans span about 10 mm between the shortest and the tallest.

Why None of Them Has a Bypass Valve

FRAM and K&N's HP-1011 page both state no bypass valve, and WIX and Baldwin list none. That is normal for this family: on many GM V8s the filter bypass sits in the engine, and owners in a Bob Is the Oil Guy thread on block-mounted bypass valves describe it as very common on GM applications.

So the missing valve on these spec sheets is not a defect. It is one more reason to cross by part number rather than by any 13/16-16 can that happens to screw on.

PF454, PF25 and PF1218: One Family, Three Heights

The PF454 is the short member of GM's long-running 13/16-16 filter family. WIX's catalogue shows three ACDelco numbers sharing one thread and one gasket and differing only in height and valves.

WIX's 51069, its PF25 equivalent, carries the same 3.444 in by 3.100 in gasket as the 57099, and WIX's principal application for it reads "GM Family of Cars/Trucks (64-99)". The 57099 is listed for 7.4L and 8.1L trucks from 1999, which is where the PF454 picks up.

Does the PF454 Replace the PF25?

For many older Chevrolet V8s, it now does. Members of the NCRS Corvette forum report that ACDelco consolidated the PF25 into the PF454, and describe the new can as about an inch shorter, with an internal anti-drainback check valve.

FRAM's numbers back the inch. Its PF25-size part, the PH30, is 4.063 in tall on the same 3.140 in gasket ID as the PH8873, and FRAM's own PH8873 application list reaches back to 1968 Chevrolet trucks and the 1990 and 1991 Corvette.

Where the Lookups Merge the Two

The manufacturers do not agree on whether a PF25 and a PF454 are one filter or two.

• K&N merges them. Its HP-1011 interchange list carries the PF25 and the PF454 together, alongside both FRAM's PH30 and PH8873.
• WIX keeps them apart for ACDelco, but not everywhere. It sends the PF454 to the 57099 and the PF25 to the 51069, yet its lookup for the Mobil 1 M1-111A and the Champ PH454 returns both parts.
• Baldwin keeps them apart. Baldwin's search sends the PF454 and FRAM PH8873 to its B1438, and the PF25 to its B27. The B27 is 111.1 mm long and lists no anti-drainback valve, against 81.0 mm for the B1438.

Even the PF25 equivalents disagree with each other: 97 mm for WIX, 103 mm for FRAM's PH30 and 111.1 mm for Baldwin. On an older V8 with room to spare, the taller PF25 size holds more oil; the PF454 is the one to fit where clearance is tight.

Going Longer on an 8.1L

Some 8.1L owners fit the PF1218 size for extra capacity. In a 2018 Bob Is the Oil Guy thread on the 8.1L, owners reported that the 132 mm WIX 51060 fits two-wheel-drive trucks but not four-wheel-drive ones, where the front driveshaft leaves too little room.

That is one thread's experience rather than a GM statement. GM's own number for these engines is the short 25324052.

What the PF454 Fits

WIX's principal application for the 57099 reads "Chev/GMC Trks + Vans w/ 7.4L, 8.1L (99-12)", and Baldwin describes the B1438 the same way. In practice that means the big-block trucks and vans:

• Chevrolet and GMC 2500 and 3500 pickups, from the 1999 C/K trucks with the 7.4L through the 2001 to 2006 Silverado and Sierra HD and the 2007 Classic with the 8.1L
• Suburban 2500, Yukon XL 2500 and Avalanche 2500 with the 8.1L
• Express and Savana 3500 vans from 1999 to 2002
• Motorhome and commercial chassis built on the same engines, which FRAM lists under Workhorse, Winnebago, Blue Bird and other brands

The PF454 is also the current fit for many older GM V8 cars and trucks that originally took the PF25, as covered above.

Is the PF454 the Same as the PF52?

No. The PF52 crosses to WIX 51036, a 74 mm wide can on an M18 x 1.5 metric thread with a 2.430 in gasket ID. It belongs to a different GM family, covered in the ACDelco cross reference, and will not thread onto a PF454 engine.

How to Cross Reference a PF454

1. Check that you have the ACDelco number, not a Purolator "PF 454", which is a fuel filter.
2. Use FRAM PH8873, WIX 57099, Purolator L15313, K&N HP-1011, Baldwin B1438, NAPA Gold 7099 or Bosch 3322 for an 8.1L or 7.4L truck.
3. Measure the clearance if you want a taller can. The PF25 size fits where there is room; the PF1218 size has been reported to clear only on two-wheel-drive trucks.
4. Cross by part number, not by look. The PF52, which WIX lists for GM cars and trucks from 1980 to 2005, is a metric-thread filter and will not thread on.

Frequently Asked Questions

What is the WIX equivalent of the ACDelco PF454? The WIX 57099, or the 57099XP in WIX's synthetic blend line. WIX's lookup returns both for the PF454, the GM 25324052 and the FRAM PH8873. WIX rates the 57099 at 3.306 in tall on a 13/16-16 thread with an anti-drainback valve and no bypass valve.

What FRAM filter replaces the PF454? The FRAM PH8873. WIX, Baldwin and K&N all pair it with the PF454. FRAM's page gives a 3.050 in can on a 13/16-16 thread with a silicone anti-drainback valve and no bypass valve, which makes it the shortest of the common equivalents.

Can I use a PF25 instead of a PF454? They share a thread and gasket, so a PF25-size filter screws on, but it is half an inch to just over an inch taller depending on the brand. On a 7.4L or 8.1L truck check the clearance first. On older V8s the PF454 is what ACDelco now supplies in place of the PF25.

Does the PF454 have a bypass valve? No. FRAM and K&N state that their PF454 equivalents carry no bypass valve, and WIX and Baldwin list none. Owners describe the bypass on many GM V8s as built into the engine side of the filter mount, which is why the filter does without one.

What to Do Next

If your truck has the 8.1L or the 1999-on 7.4L, any equivalent in the first table fits. If you are working on an older V8 and want to know why the box in your hand is shorter than the filter you took off, the PF25 section above is the answer, and the ACDelco cross reference linked above covers the rest of GM's PF numbers.
