I won't buy Purolator a/fs for my truck because they don't fit the air box. The Purolator a/f gaskets are missing a rib that seals the air box. Without the rib, the two halves of the housing can move around and dirt can get past the filter. I first noticed this back in 2006 or so when I bought one without looking at it first. I have checked Purolators on the shelf since then and the gaskets are still way too thin.
Personally, I like Fram a/fs. The gaskets make a very tight seal and I have never had a quality issue with a Fram a/f.
It isn't brand loyalty either. I have used Purolator oil filters without a second thought, their a/fs just don't fit my application. I won't and have never bought a Fram oil filter, but their a/fs work great in my application.
I think the Purolator will work fine IF it seals the air box good. Just check the filter before buying to make sure it matches the original.
