With nine different gas-engine vehicles at my place, I invest a lot of time switching fluids and filters. I don’t have strong brand loyalty regarding consumables, but NAPA Gold has been my preferred oil filter. They are reliable, easily accessible, and until lately, made in the USA. This month, when I intended to stock up for my Montero’s upcoming oil change, I was disappointed to spot “made in China” on the box of my NAPA Gold 1334 filter. This prompted me to do some research that ultimately introduced me to a new product that I’m more enthusiastic about anyway.
NAPA’s movement of filter production isn’t recent news. The auto parts retailer switched suppliers from WIX to Premium Guard in 2023, and discussions about the change have been circulating in forums for years. I suspect I’ve been buying outdated stock in the 1334 size used by my Montero for the last few changes—or perhaps I just didn’t examine the package closely last time.
However, it motivated me to reconsider my filter choices, and I was reminded of a brand named Baldwin that I had intended to explore.
Baldwin is a long-standing filter brand (air, oil, etc.) utilized in agricultural and industrial applications and has been for countless years. In fact, when I first acquired my Montero around 2018, another owner suggested them to me. Yet, I somewhat overlooked it because you hardly see them on the shelves of part stores. (For no logical reason, I enjoy purchasing my oil, filter, and drain-plug kits in person at a physical store.)
The Baldwin filter suitable for my 1998 Mitsubishi Montero’s 3.5-liter V6, B7243, was not as easy to locate as the common oil brands that you frequently see advertised—they are primarily available through industrial supply websites instead of auto parts retailers. Walmart can acquire one for you as well. They are extremely affordable, and to my delight, still made in the USA.
When my Baldwin filter arrived, I observed it was more “tall and slender,” whereas the NAPA Gold unit appeared “short and stout,” relatively speaking, of course. They felt about the same weight, but comparing specifications revealed noteworthy differences.
| Baldwin B7243 | NAPA Gold 1334 | |
|---|---|---|
| Height | 3.44″ (87.3mm) | 3.19″ (81mm) |
| OD | 3.03″ (77mm) | 3.25″ (83mm) |
| Thread | M20 × 1.5 | M20 × 1.5 |
| Bypass valve | 20 PSID | 8–11 PSID |
| Micron rating | 18 nominal / 40 absolute | 21 nominal |
| Media | “Microlite” (Baldwin proprietary) | Glass-enhanced cellulose |
| OEM cross-reference | Mitsubishi MD352626, MZ690116 | Generic fit |
Here are the three key insights from the data I found about these filters.
1. The bypass valve gap is important. 20 PSID vs. 8–11 PSID represents a considerable difference—it’s almost double. The B7243 features both an anti-drainback valve and a 20 PSID by-pass valve. A filter that bypasses at 8–11 psi will divert unfiltered oil around the element at relatively low differential pressures—for instance, during a cold start in winter when oil is thick, or when the filter is moderately loaded. The Baldwin maintains its threshold until 20 psi. For a V6 engine in a 4×4 that experiences diverse conditions, that’s a significant benefit.
2. The Baldwin micron rating is superior. The B7243 has a rating of 18 micron nominal, compared to 21 micron nominal for the NAPA Gold. Baldwin also lists an absolute rating of 40 microns, which represents a stricter standard (nominal ratings permit a percentage of particles to pass; absolute means virtually none above that size escape). The NAPA doesn’t provide an absolute rating at all, which, I believe, indicates something.
3. The Baldwin is a filter tailored for a specific application, not a generic one. The B7243 directly substitutes Mitsubishi OEM part numbers MD352626 and MZ690116—these are the actual filter numbers from the Mitsubishi factory for your engine. The NAPA 1334 matches to 559 different filters across various vehicles, including cars, trucks, tractors, and industrial equipment. It fits the Montero, but it wasn’t engineered specifically for it. The B7243 was.
Will I notice any difference in performance by using this Baldwin filter? In everyday use, certainly not. And the NAPA Gold unit, visually, seemed satisfactory. However, my Mitsubishi has over 220,000 miles on it and is used for off-road training. I want this vehicle to endure as long as possible, and in any case, I make an effort to buy American-made when practical.
With excellent specifications and domestic manufacturing at a reasonable price, this Baldwin filter is an obvious choice. Here’s hoping Baldwin remains independent and retains its quality (and never is acquired and dismantled by private equity). The brand doesn’t produce filters for every passenger vehicle, but it has a fairly extensive selection for trucks and SUVs.
Many mechanics have recognized the quality of these red filters for years, but if you weren’t aware, you’re welcome. You can utilize Baldwin’s filter finder to see what they offer for your vehicle.
