I purchased a 07 3500 4x4 ram with the 6.7 Cummins last June. I went
to Cummins and bought a oil filter for it and it was the wrong one.
When I took it back they said there are two different 6.7 engines for
2007 the first which I have was used until July first. The second is
for use after july.
Cummins told me the difference was the EPA set up for emissions.
The two oil filters are the same size but the inlet on the oil fliter
for the july and after model is little bigger. So when I tried to
install it, ot slipped right over the threads.
So when they gave me the second filter it worked just fine. Which is
the same one used on the 5.9 model.
I am just wondering why the oil filter for the new motor would be
different. How is that relativenet to the EPA setup for emissions on
the newest motor. Mine clearly saids 6.7 on the top of the motor.
Thank you all for your information.
