To all the replys above, don't make the assumtion that the Fram HP filters are of the same low quality as a regular Fram filter.

The HP2 and HP4 fits GM, the HP1 and HP3 fits Ford and Mopar.
Difference of 1&2 is length, 1 is 5.75" long, 3 about 2" shorter. Difference of 2&4 is burst pressure 500vs375.



The burst rate may be better but that has nothing to do with the poor quality of the filtration elements..

I am truckless..
