PH51A Oil Filter Cross Reference / Replacement Numbers

The PH51A oil filter is a cross reference to the following part numbers:

OE and aftermarket part numbers are listed for reference only. All brand names belong to their respective owners, and IXIN is not affiliated with them. For official Luber-Finer numbers, you can also use Luber-finer’s online parts lookup and compare the result with our PH51A oil filter data.

Why Oil Filter Replacement Matters

Engine oil constantly picks up metal particles, soot and sludge. An oil filter removes these contaminants while the oil circulates, protecting bearings, pistons and other moving parts from abrasive wear. A clogged or poor-quality oil filter lets dirt through, which shortens engine life and can lead to costly repairs. Replacing the PH51A oil filter with every oil change, at the interval the vehicle maker recommends, keeps the oil clean and the engine protected.

Why Choose IXIN’s PH51A Oil Filter

• Factory-Direct Supply: IXIN manufactures filters in its own factory in Linxi County, Hebei. You deal with the manufacturer, not a trading company.
• Wide Cross-Brand Coverage: One PH51A oil filter replaces Luber-Finer, ACDelco, GM, Purolator and Pronto references, which helps distributors simplify inventory.
• Defined Size for Easy Matching: A clear 76 mm outside diameter, 113 mm height and M18 x 1.5 thread make it simple to compare the PH51A oil filter against the filter you are replacing.
• Anti-Drain Back Valve: The anti-drain back valve helps keep oil in the filter when the engine is switched off, which supports quicker oil pressure build-up at the next start.
• Quality Filter Paper: We build our filters with media from a dedicated filter paper manufacturer. Read how high-quality filter paper improves truck air, oil and fuel filter performance.
• Customization Available: We support customization of filter paper quality, metal thickness and packaging for your market.
• Fast Delivery: In-stock items usually ship in 5 to 10 days. Made-to-order items take 15 to 45 days, depending on quantity.

Installation and Maintenance Notes

1. Switch off the engine and let it cool. Place a drain pan under the filter.
2. Drain the oil as described in the vehicle manual, and unscrew the old filter with a filter wrench.
3. Check that the old rubber seal came off with the filter. A leftover seal can cause leaks.
4. Wipe the mounting surface clean, and lightly oil the seal of the new PH51A oil filter.
5. Screw the new filter on by hand until the seal touches the mounting surface, then tighten as specified by the vehicle maker.
6. Refill with the correct oil to the right level, start the engine and check for leaks.
7. Replace the filter with every oil change, at the interval recommended by the vehicle maker.
