AC Delco Oil Filter Cross Reference Chart

ACDelco sells oil filters under two current aftermarket lines, Gold and Silver, both built to fit GM vehicles and most other makes. The PF number on the can is a GM catalogue number, and the seven cross references below are confirmed against WIX's and K&N's own manufacturer catalogues rather than an aggregator chart. Two of those numbers, PF48 and PF64, look interchangeable on one manufacturer's index and are not.

ACDelco Gold vs Silver: What the Two Lines Actually Are

ACDelco's current parts catalogue lists Gold and Silver as the two aftermarket lines GM backs directly, separate from ACDelco Original Equipment, which is the true factory-fit line rather than an aftermarket replacement. Gold carries a 24 month, unlimited mile warranty. Silver carries 12 months, unlimited mile.

The "Professional" name still appears on individual product pages, but GM's own classification tag resolves it to Gold rather than treating it as a third line. Part C3019 is titled "ACDelco Professional Engine Oil Filter" on its GM Parts product page, and its own spec table lists Classification: Gold. A plain PF661 spin-on carries the same Gold classification. Professional reads as a legacy label sitting inside the Gold tier, not a parallel product line.

Silver is the standard-replacement tier. GM's product page for PF63A describes it as "ACDelco Silver Black Shell Engine Oil Filters," Classification: Silver, Grade Type: Standard Replacement. That page is also where a naming trap shows up: the Silver-line filter for this application is PF63A, not the plain PF63 that ACDelco Gold and GM Original Equipment both use for the same body style. A parts counter search for "PF63" that returns a Silver listing is returning the "A" suffix part, and the two are not the same catalogue entry even though they share a can size and a name.

Who Actually Builds an ACDelco Oil Filter

ACDelco does not manufacture filters. Owners and shop mechanics researching this question consistently point to Champion Laboratories as ACDelco's historical filter supplier, one of several private label programs Champion ran alongside FRAM, which is the reason ACDelco's construction details have tracked so closely with FRAM's over the years. No ACDelco or GM press release names Champion Laboratories directly, so this is owner-researched and cross-referenced rather than manufacturer-confirmed.

That relationship sits inside a supply chain that changed completely between September 2025 and June 2026, and it is worth spelling out because most "who makes ACDelco" pages online still describe the old ownership as current. First Brands Group, which owned Champion Laboratories, filed Chapter 11 in September 2025, and by early 2026 Champion Laboratories itself had filed bankruptcy. The Albion, Illinois plant that built Champion's automotive filters closed permanently on 23 February 2026, after a buyer deal for the facility fell through, according to a letter to employees from First Brands Group.

Premium Guard Inc (PGI) then acquired First Brands' Champion Labs assets in phases through March and April 2026, and on 24 June 2026 announced it would reopen the Albion facility, restoring nearly 200 jobs and pulling in equipment from the legacy FRAM plant in Greenville, Ohio. PGI's own release states plainly that it closed the acquisition of "First Brands Group's Champion Labs assets," which confirms Champion Labs was First Brands property at the time of the collapse, not the older, differently-owned Champion Laboratories that operated under Carlyle Group ownership before 2020.

What is not established anywhere in PGI's public statements is a direct claim that PGI now supplies ACDelco specifically. PGI's releases name FRAM, Autolite, TRICO, ANCO and Luber-finer as brands it took on. Neither GM nor ACDelco has published a supplier announcement following the Champion Labs collapse, so this article states the gap rather than closing it with a guess. If you are buying an ACDelco filter today, the honest answer is that its current manufacturing source has not been confirmed by either party involved, which is exactly the kind of construction detail that separates one brand from another even when two cans look the same.

ACDelco Efficiency and Bypass Specs, From GM's Own Pages

GM's product pages for both the Gold and Silver lines carry the same efficiency figure. The Silver PF63A listing states "98% multi-pass filtering efficiency at 25 to 30 microns," and the Gold C3019 listing carries the identical wording. Both also describe a burst strength "five times greater than most engine oil operating pressures," valid as long as normal operating oil pressure does not exceed 51 psi.

This figure comes from GM's own e-commerce product copy rather than a standalone spec-sheet PDF. No separate ACDelco data sheet publishing this number independently was found, so treat it as GM's stated figure rather than a third-party-tested result, and note that it is not tied to a named test standard like ISO 4548-12.

Bypass valve pressure is where GM's documentation gets specific, and only for one comparison. GM's service bulletin 17-NA-157, hosted publicly on NHTSA's technical bulletin server, states that PF48 and PF48E open their bypass valve at 15 psi (100 kPa), while PF63 and PF64 open at 22 psi (150 kPa). The bulletin frames this as a safety distinction: a filter with a bypass opening at 15 psi or below on an engine designed for the 22 psi group can let unfiltered oil circulate and damage bearings. GM's own PF63A spec table lists a Bypass Relief Valve Setting of 22, matching the bulletin's figure for that engine family.

That bulletin covers Small Gas Engine, Large Gas Engine, High Feature V6 Gen 2 and Small Block Gen 5 families specifically. No bypass pressure figure for PF47, PF52, PF57, PF61, PF2232 or PF1218 was found published anywhere by GM, so none of those numbers appear in this article. If GM publishes one later, it belongs in a spec table. Until then, stating one would be a guess dressed as a fact.

ACDelco Cross Reference Chart

The numbers below are each confirmed on two independent manufacturer catalogues: WIX's own part lookup and K&N's own cross reference index. Where the two disagree or one is silent, that is noted rather than smoothed over.

One row deserves a direct warning rather than a quiet listing. K&N's own cross-reference pages send both PF48 and PF64 to the same part, SO-1017. GM's service bulletin above states those two filters open their bypass valves at different pressures, 15 psi against 22 psi, on engines where that difference is the entire safety point being made. Treat any chart, including this one, that maps PF48 and PF64 to a single equivalent as a cataloguing shortcut rather than a confirmed interchange, and check the bypass rating on whatever you actually buy.

PF63 itself carries a longer, separately researched cross reference covering its GM applications, its Ford-only WIX counterpart mixup, and why some retailer listings wrongly show it fitting an F-150. That research is not repeated here.

FAQ

Is ACDelco Gold the same as ACDelco Professional?

Functionally yes. GM's own product classification tags both under Gold, and the Professional name appears to be a legacy label still printed on some packaging and product titles rather than a distinct catalogue tier with its own specs or warranty.

Does ACDelco PF48 fit where a PF64 fits?

No. GM's service bulletin states the PF48 and PF48E open their bypass valve at 15 psi while the PF63 and PF64 open at 22 psi, and warns that the lower setting can let unfiltered oil circulate on engines designed for the higher one. Some cross-reference charts list them as equivalent; GM's own documentation does not support that.

Who makes ACDelco oil filters right now?

Champion Laboratories built them historically, but Champion Labs' parent First Brands Group collapsed through bankruptcy in 2025 and 2026, and the Albion, Illinois plant closed in February 2026. Premium Guard Inc acquired the Champion Labs assets and reopened Albion in June 2026, but neither PGI nor GM has stated that PGI now supplies ACDelco specifically.

Is ACDelco Silver a lower quality filter than Gold?

It is a lower tier by GM's own classification, with a 12 month warranty against Gold's 24 months, and GM markets it as a standard-replacement option rather than the premium line. Both lines carry the same published 98% multi-pass efficiency at 25 to 30 microns on the product pages checked for this article.

Match the bypass pressure before you match the can size. An ACDelco cross-reference that only tells you two filters thread onto the same block is not telling you whether they protect the engine the same way, and the PF48/PF64 pair above is the clearest published proof that they can look identical and still be wrong for each other.
