AC Delco PF63 vs. PF63e Ölfilter

AC Delco upgraded the PF63 to the PF63e. The company modified the bypass pressure relief from 12 to 22 pounds.

It indicates that the bypass pressure reliever is working around the outside edges of the oil filter. When the valve opens the pressure on both sides is pretty close if the filters are working properly.

The oil is heavy on a morning start. It opens and lets in unfiltered crude oil. However, it doesn't matter. Because it can't flow, you put more pressure on one side than the other. That's why you shouldn't starve the engine when the oil is getting thinner.

Below are some of the key differences between the AC Delco PF63 and PF63e oil filters.

inlet holes

The PF63e features eight intake holes and a bypass valve on the bottom. It also includes a nylon plastic inner cage and plenty of grooves. It includes lots of threads and a nitro rubber gasket that you can remove.

The PF63, on the other hand, has six intake holes and a bypass valve with holes below the metal core, although it doesn't have as many threads as the PF63e. There are about three threads. It also features a nitro rubber gasket that you can easily remove.

The baseplates are very different from the PF63e, the inner core.

The PF63e weighs 228 grams while the PF63 weighs 273 grams. The PF63e's baseplates weigh around 108 grams, while the PF63's baseplates weigh 100 grams. The PF63e filter element weighs 35 grams, while the PF63 filter element weighs 893 grams. In addition, the PF63e media weighs 22 grams while the PF63 media weighs 19 grams.

The PF63e's bypass valve weighs ten grams, while the PF63's bypass valve weighs eight grams.

base plate

The base plates of the PF63e have more holes than those of the PF63. It contains about 13 holes spread across the filter and two other holes of the same size. Also, the PF63e has more grooves and threads than the PF63.

However, the bottom panel of the PF63 is more appealing than that of the PF63e. It seems sturdier, and the return valves are nitro rubber. They also do a good job of camouflage the gaps.


As a glued seam, the PF63e has approximately 65 pleats. It comes with felt and caps. It also has a significant amount of space. It is a cellulose filter medium with a micron rating of 98 between 25 and 30 microns.

There are approximately 51 pleats in the inseam of the PF63. The filter media is comparable to the PF63e and has the same filter counts. It just has fewer wrinkles. The folds are deeper as the metal end caps bypass the value down there.


In terms of thickness, both oil filters are about the same. Both have a thickness of 0.41 mm. However, the width is the difference. The PF63e is 3.44 inches wide while the PF63 is 3.03 inches wide.

When cut open and spread out, they even out due to the larger folds of the PF63e. When extended they are nearly identical: the PF63e is 45 inches long and the PF63 is 45 ¼ inches long.

The PF63e is 0.83mm thick at the seams, while the PF63 is 0.87mm thick.

While both oils have their distinct differences, they also have their similarities. A new torque standard has been made available. This standard is for installing ACDelco replacement oil filters for GM gasoline powered vehicles such as the AC Delco PF63 and PF63e. The company created the updated standard in response to potential oil leaks. These leaks may have occurred at a previous oil change service. Sometimes the oil leak may not appear for many thousands of kilometers.

Is the AC Delco PF63e better than the PF63?

According to ACDelco, the better performance of the new filters is due to a revised bypass valve design. This design includes a compression spring loaded nylon disc that outperforms the current filter. These filters meet the performance requirements of the GM Powertrain.

The following improvements have been made:

  • The opening pressure of the bypass valve has been increased from 100 to 150 kPa and is statistically more competent.
  • Increased resistance to water retention
  • The filter material is no longer spilled with glue that could clog the filter area.
  • Excellent performance in cold weather down to -30°C with Dexos1 oil. Hot oil resistance is improved by removing the adhesive.
