Oil filter cross reference - Fram PH7325, What filters will fit my aftermarket oil tank? Options

[Eddie914]

I'm trying to find what oil filters are available for my 3.2 powered 914/6 conversion with a one-off oil tank mounted in the original battery location.

The car was converted by the previous owner and he was not able to provide any additional information.

The car came with a Fram PH7325 oil filter that my local auto parts stores do not stock any more.

CM Filters (Canton Mesa) has a cross reference than indicates that their model 25-282 is interchangable with the Fram PH7325.

The CM specifications indicate that the 25-282 has a 20mm thread, 2 5/8" O-Ring and 4 1/4" length.

The CM 25-282 also fits 91-94 911 Turbo, 82-up 944 and 78-up 928.

Any Suggestions?

Thanks

Eddie

I just read the 'oil filter study'. Specifically, the FRAM part. The author did not buy/disect a FRAM diesel specific filter, but the FRAM diesel filters I had been buying(PH2977A) were comparable in price ($7) to the 'Fram Tough Guard' which the author seemed to like:

"This filter has an improved filter element with more surface area (248 sqin), a heavy silicone anti-drainback valve with a good sealing surface, the same plastic pressure relief valve but with an integral screen to keep out large particles, and enough inlet holes for good flow. In my opinion, the only real drawback to this filter is that it is capped on each end with cardboard instead of metal."

No direct evidence, but it looks like I have been using 'Fram Tough Guard' oil filters on the same /6 engine for the past 200K miles.

FRAM good/bad, mute point now as the FRAM PH2977A went out of production a few years ago. It has taken me until now to use up my stash. I'll be using the Purolator now.
