NAPA 1372 Oil Filter Cross Reference and Fitment Guide
The NAPA Gold 1372 is a spin-on oil filter covering a wide range of Ford, Lincoln, Mercury, and Mazda vehicles from the early 1990s through the 2010s. Its verified cross references include the FRAM PH2, WIX 51372, Purolator L24651, and Motorcraft FL820S. Any filter sharing its M22 x 1.5 thread size, 3.668 in OD, and bypass valve spec is a valid physical replacement.
What Is the NAPA Gold 1372 Oil Filter?
The NAPA Gold 1372 is a standard spin-on oil filter from NAPA's Gold tier, their mid-grade conventional filter line. NAPA Gold filters were built by WIX Filtration for decades, though NAPA moved most light duty Gold spin-on production to other suppliers between 2023 and 2025. The NAPA Gold numbering convention still drops the leading digit from the WIX part number: NAPA Gold 1372 corresponds to WIX 51372.
Inside, the 1372 uses enhanced cellulose media, a silicone anti-drainback valve to prevent dry starts, and a bypass relief valve that opens under high differential pressure to protect the engine when the filter is heavily loaded with debris.
What Vehicles Does the NAPA 1372 Fit?
The NAPA 1372 covers a broad range of Ford, Lincoln, and Mercury vehicles from approximately 1991 to 2014, plus select Mazda and Cadillac applications. It is the direct aftermarket replacement for the Motorcraft FL820S, which is the OEM filter for Ford's V6 and V8 gasoline engine families across this era.
Ford vehicles commonly using this filter:
- Crown Victoria (1992–2011)
- E-Series Econoline (E-150, E-250, E-350): select years
- Escape (2001–2008)

This fitment spans Ford's 4.0L SOHC V6, 4.6L V8, 5.0L V8, 5.4L V8 Triton, and 6.8L V10 Triton engine families, among others. Fitment spans decades and many platforms, so always verify by entering your year, make, model, and engine into a parts lookup before purchasing.
NAPA 1372 Specifications
Cross reference compatibility depends on matching these physical specifications. Any replacement filter must share the same thread size, gasket diameter, and bypass valve range.
| NAPA 1372 | What the spec sheets say |
|---|---|
| Thread size | M22 x 1.5 |
| Outside diameter | 3.668 in (93.2 mm) |
| Overall height | 3.836 in (97.4 mm) |
| Bypass valve pressure | 22 PSI |
| Burst pressure | 275 PSI |
| Anti-drainback valve | Yes (silicone) |
| Media | Enhanced cellulose |
| Micron rating | 21 microns |
| Typical service interval | Up to 5,000 miles |
The M22 x 1.5 thread is a metric thread standard used across many Ford V8 and V10 applications. The 22 PSI bypass valve setting is notably higher than what is common on many four-cylinder and smaller V6 filters, which typically run 8 to 12 PSI. This higher bypass pressure is consistent with what Ford specifies for these high-volume V8 applications.

How to Read This Chart
Find your current filter's brand and part number in the left column. Read across to the brand you want to switch to. A technician moving from a Motorcraft FL820S to an aftermarket filter for a fleet service would choose the NAPA Gold 1372 or WIX 51372 for conventional oil intervals, or the WIX 51372XP for extended synthetic service. The physical fit is the same across every row in this chart. For a broader look at how oil filter cross references work across all applications, including how to use the major lookup tools, see our full guide.
Is the NAPA 1372 the Same as the WIX 51372?
The NAPA Gold 1372 and WIX 51372 are the same filter manufactured by WIX Filtration and sold through different retail channels. NAPA's numbering convention drops the leading "5" from the WIX number. This pattern is consistent across the NAPA Gold line: NAPA Gold 1056 is WIX 51056, NAPA Gold 1348 is WIX 51348, and so on.
Inside the box, the filter is built to the same spec. The label and the retailer differ. If you normally buy WIX and only have NAPA available, or vice versa, there is no quality compromise in switching between these two part numbers.
NAPA 1372 vs Motorcraft FL820S: Which Should You Use?
The Motorcraft FL820S is Ford's own OEM replacement filter for all the vehicles on the fitment list above. It is built to the same specification as what Ford installed at the factory.
The NAPA Gold 1372 and WIX 51372 are aftermarket equivalents that match the FL820S in thread size, gasket diameter, bypass valve pressure, and overall dimensions. In practice, both are well-made conventional-service filters appropriate for factory oil change intervals.
The case for the FL820S: if you want the closest match to the factory filter, particularly on an in-warranty Ford vehicle, the Motorcraft filter is the straightforward choice. It is available at Ford dealers, AutoZone, and O'Reilly.
The case for the NAPA 1372 or WIX 51372: professional shops often stock NAPA Gold or WIX because they cover a wide range of applications at a slightly lower price point than Motorcraft retail. The filter quality is comparable at conventional oil intervals.
For vehicles running full synthetic oil at extended intervals, none of these conventional-cellulose filters is the right choice. Step up to the WIX 51372XP, FRAM XG2, or Purolator PL24651 PureONE, which are rated for longer service windows with synthetic oil.
Upgrading from the NAPA 1372: Extended Performance Options
The NAPA Gold 1372 and its direct equivalents use conventional enhanced cellulose media with a typical 5,000 mile service rating. If you are running full synthetic oil or extending oil change intervals, you need an upgraded filter that matches the extended service interval.
| Filter | Media | Rated Interval |
|---|---|---|
| WIX 51372XP | Synthetic micro-glass | Up to 10,000 miles |
| NAPA Gold 1372MP | Synthetic micro-glass | Up to 10,000 miles |
| Purolator PL24651 (PureONE) | Full synthetic | Up to 10,000 miles |
| FRAM XG2 (Ultra Synthetic) | Full synthetic | Up to 20,000 miles |
If your Ford runs on a 5,000 mile conventional oil schedule, the NAPA Gold 1372 or Motorcraft FL820S is appropriate. If you have switched to full synthetic at 7,500 to 10,000 mile intervals, the WIX 51372XP or Purolator PL24651 are the right call. For 15,000 mile or longer schedules, the FRAM XG2 is rated for that extended service.
Where to Buy the NAPA 1372

FAQ
What does the NAPA 1372 cross reference to?
The NAPA Gold 1372 crosses to the WIX 51372, FRAM PH2, Purolator L24651, and Motorcraft FL820S. All share the same M22 x 1.5 thread, 3.668 in OD, and 22 PSI bypass valve spec. The WIX 51372 is manufactured on the same production line as the NAPA Gold 1372 and is a direct physical equivalent.
Is the NAPA 1372 the same as the WIX 51372?
Yes. NAPA Gold filters are made by WIX. The NAPA numbering convention drops the leading "5" from the WIX number. NAPA Gold 1372 and WIX 51372 are the same filter from the same factory, sold under different labels through different retail channels.
What vehicles use the NAPA 1372 oil filter?
The NAPA 1372 fits Ford, Lincoln, Mercury, and Mazda vehicles from approximately 1991 to 2014. It is the aftermarket equivalent of the Motorcraft FL820S, covering Ford's 4.6L, 5.0L, 5.4L, and 6.8L V8/V10 engine families used in the F-150, Mustang, Explorer, Expedition, Crown Victoria, and many other models. Always verify by entering your exact year, make, model, and engine in the parts store's fitment lookup before purchasing.
Can I use a FRAM filter instead of the NAPA 1372?
Yes. The FRAM PH2 is a verified cross reference for the NAPA Gold 1372. They share the same M22 x 1.5 thread, gasket diameter, and bypass valve spec. For conventional oil intervals up to 5,000 miles, the FRAM Extra Guard PH2 is appropriate. For synthetic oil or extended intervals, use the FRAM Ultra Synthetic XG2.
How often should I change the NAPA 1372?
The NAPA Gold 1372 uses conventional enhanced cellulose media. It is rated for conventional oil service intervals, typically 3,000 to 5,000 miles depending on driving conditions and your vehicle manufacturer's recommendation. If you are running synthetic oil, step up to the WIX 51372XP or FRAM XG2, which are rated for 10,000 to 20,000 mile intervals. Your vehicle manufacturer's recommended interval always takes priority over filter marketing claims.
What is the bypass valve pressure on the NAPA 1372?
The NAPA Gold 1372 (and its cross reference WIX 51372) has a bypass valve set at 22 PSI. This is higher than the 8 to 12 PSI bypass settings common on smaller four-cylinder applications, and is consistent with what Ford specifies for the V8 and V10 engines this filter serves.
If your Ford or Lincoln uses this filter and you are switching to full synthetic oil, the most impactful cross reference upgrade is the WIX 51372XP or FRAM XG2. Same thread, same fit, significantly better media for the longer drain interval.
