ACDelco GM Original Equipment PF63 (12735811) Engine Oil Filter

If you’re running a Chevrolet, GMC, Buick, or Cadillac, especially a heavy-duty model like a Silverado or Sierra with the 6.6L engine, this ACDelco PF63 (12735811) is a no-brainer. It’s the genuine OE filter—designed, tested, and validated by GM—so you know it’s optimized for your engine from the start.   What sets it apart? It features Duraguard filter media—an efficient, high-capacity barrier that catches harmful particles without choking oil flow.   The nylon poppet-style bypass valve works with a higher bypass setting tailored to modern GM engines, ensuring you get filtered oil right when you need it—even under high flow.   In terms of fit and finish, this filter is built to OEM precision. It screws in cleanly (thread size M22×1.5), fits the correct housing dimensions, and doesn’t let any nasties bypass the media.   Recent construction tweaks—like larger inlet holes and removal of the extra outer baseplate—are smart updates aimed at improving oil flow and ease of installation, while the internal filter setup remains reliable.    Lots of users report no issues and smooth performance: “This OEM filter is great—no complaints here. Definitely recommend to anyone doing their own maintenance.”  And with a ~4.7/5 average from 112 reviews and nearly all users recommending it on AutoZone, this filter earns its stripes.  The Short Version: • OEM-grade—built to GM specs • High-capacity, efficient media—blocks contaminants without restriction • Proper bypass valve—maintains flow under all conditions • Updated design improvements—better flow and installability • Trusted by users—excellent performance reviews
