PF48/PF48E Redesign

[newdude]

The PF48E primary performance improvement relates to the relief valve design. The PF48E has a compression spring loaded nylon poppet that outperforms the current valve design.

 

Other benefits:

• Element integrity (collapse strength) is increased by 25%. This is because the nylon cores are perfectly round.
• Filter media, which is unchanged, is no longer potted in adhesive which blocks filtration area at each end.
• Filtration performance (efficiency and capacity) are both unchanged.
• The filter shell configuration is unchanged. Existing cap wrenches continue to fit.
• Hydrostatic burst and impulse fatigue performance are both unchanged.
• Relief valve performance is much improved and statistically more stable.
• Hot oil durability is improved by elimination of adhesive.
• Cold weather performance (-30 C) with dexos 1 oil is excellent.
• Improved level of robustness to water accumulation.
• Nitrile material used in the sealing gasket and the anti-drainback valve is unchanged.
• PF48E filters meet performance specifications as defined by GM Powertrain.
• PF48E filters will be used in OE production in the near future.

 

 

No idea as to what the guts look like but we will find out soon enough. Sames body, same media but no more glue and better relief valve. Honestly, I'm hoping its better or an improved E-Core if it is now to become an E-Core.

Got some in today. Here some pics.

The PF46 and PF46E are the same way. I stuck with the original 46 on my truck.

Or you may substitute the PF63 for the PF48.

I prefer the PF63. A little more filter capacity doesn't hurt!

Interesting to see that the redesign is even shorter. With the technology we have today and how far engine oils have come along, I guess the engineers feel that the need for larger filters isn't warranted like in days past. Seems that oil filters keep getting smaller and smaller. Well on GM's that is. Ford still uses a larger filter.

So I assume the PF48E is the "Ecore" design?

 

BTW- if you do an oil analysis you will find no difference in you oil using the PF63.

Yea you can see the plastic cage in the pics above vs. the regular PF48.

I only found the 48e in stock last week so that's what I went with. Although the one I removed was the 63 which was a drastic change in terms of size.

 

I'm knocking on wood that I don't have any issues!

[newdude]

Bumpity bump!

 

Good news!

 

Those of you that use the PF63 (2014 1500 Silverado/Sierra all engines, Traverse/Acadia/Enclave/Outlook/Equinox/Terrain with the 3.0/3.6 V6) there is a PF63E coming! Yay! ...sarcasm...

 

 

 

The PF63E primary performance improvement relates to the bypass valve design. The PF63E has a compression spring loaded nylon poppet that outperforms the current valve design.

 

Other benefits:

• Element integrity (collapse strength) is unchanged.
• Filter media, which is unchanged, is no longer potted in adhesive which blocks filtration area at each end.
• Filtration performance (efficiency and capacity) are both unchanged.
• The filter shell configuration is unchanged. Existing cap wrenches continue to fit.
• Hydrostatic burst and impulse fatigue performance are both unchanged.
• Bypass valve opening pressure is increased from 100 to 150 kPa and is statistically more capable.
• Hot oil durability is improved by elimination of adhesive.
• Cold weather performance (-30 C) with dexos1 oil is excellent.
• Improved level of robustness to water accumulation.
• Nitrile material used in the sealing gasket and the anti-drainback valve are unchanged.
• PF63E filters meet GMPT performance specifications as defined by GM.
• PF63E filters are expected to be used in OE production in the near future.

I was able to find a case and a half of the classic PF48's for my '13, and a few classic PF61's for my G6 GT. None of those cheap junk E-Cores will end up on my vehicles. Since GM discontinued the PF24, I have been using Baldwin B39's on all of my classic Pontiac V-8's. They are a superb quality filter!

Looks like a classic cost cutting project to me but I have no proof of that.

A little more size does not always mean more filtering. There are a lot of variables like the micron rating, the filter media itself (cellulose or synthetic), and how that equates to effective flow rating and the percentage of filtration at a particular micron level. It sure isn't like we are trying to trap a pound of dirt with these filters on our motors. There is no real solid proof that a larger sized filter is more effective, and in some cases, could actually have the reverse effect. Only oil sample analysis could tell. I sure would like to see used oil samples, from the same engine on the same oil over the same time frame, one oil change using a PF48 and another oil change on PF63 to actually see if there are any differences. I highly doubt it.

 

But, I don't use AC Delco filters, so it is basically a moot issue for me.

[WilliamBos]

Probably no real advantage to using the PF63, eh?

 

Thanks for the pics. It looks like the PF48E was designed with improved flow in mind?

[dbbspider]

I have used the E core designs oil filters on several applications with no issues. I even cut some of them open to see what's going on after an oil change. I didn't see anything I need to be concerned about. Use them with confidence.
