this rev change address these ealier problems that might have been
associated with your product on the cummins turbo diesel i look forward to

Thank you for the e-mail regarding the recommended Fram oil filter for your
1999 Dodge Ram 2500 series truck with the 5. 9L Cummins diesel engine. We
welcome the opportunity to be of service.
According to our data, the PH3976 and the PH3976A are the recommended Fram
oil filters for your 1999 Dodge 2500 series truck with the 5. 9L Cummins
diesel engine. The PH3976A is a running production change improvement that
replaces the PH3976. However, the filtration media used in both versions
remains unchanged. There is considerable finger pointing, unsubstantiated
comments, and accusations directed at the aftermarket filter manufacturers,
including Fram. Yet, our representatives, that have investigated these
claims, have not found any evidence to confirm that the Fram filter is
responsible for clogging the oil flow passages in these Cummins diesel
engines.
The replacement of the PH3976 with the PH3976A is due in part to the
Chrysler claims of neoprene residue, among other contaminants found in the
engine, contributed to the engine damage. Fram voluntarily replaced the
neoprene sealant used in the end cap construction of this filter. The
redesign of this filter provides uniform continuity where the end cap meets
the tapping plate as well as reducing Chrysler's concerns by removing an
element that they believe is suspect in these engine related issues.
Again, no conclusive evidence has been presented to prove that the Fram
PH3976 or PH3976A filter is the cause of the engine damage claim issues.
The removal of the neoprene sealant was necessary to "rule out" the Fram
filter as a contributor to these engine damage claim issues.
Fram continues to stand behind and endorse the use of the PH3976 and the
PH3976A oil filters in the 5. 9L Cummins diesel engine.
Thank you for choosing Fram filters.
Cordially,
