Thankxxx again.

I just put one of the WIX super long Industrial size Filters (since I have a remote mount) I need as much weight in front on the Rocky as possible, lol). It takes the standard 'FL-1A' Mopar/Ford V8 base.

It probably holds 2 quarts and should (all else being equal) have a lower pressure drop as the Standard Wix/Napa Gold many of us use.

I would think on a race car you're not wanting/needing so fine a filtration (as smaller/finer filtration generally equates to a higher proportional restriction/pressure drop)... oil pressure supply back to the bearings at the higher RPM's is really much more critical.

A little extra oil is always good, but don't count on the larger filter with more filtering surface area improving the pressure drop as that often is not the "bottle neck". Also, improved filtration often does not equate to the size of the filter area, not to mention we have a tendency to way over kill the change interval.

I bought a bushel full of Mobil 1 filters a few years ago when a local chain had them on sale for $4, they have worked fine and look to be made to a hi quality standard with a thick canister.

The good Carquest filters were made by Wix for years. Since Advanced bought out Carquest, they are switching to Champ. When everyone is in a race to the bottom pricewise, this is what you get.
