What kind of oil filter do you guys use?

When I had my camshaft replaced recently, the Microguard (the guy at O'Reilly's told me they were a Wix brand) filter I bought for the 340 wouldn't fit with my headers because the "stock" filter they sell is too long. The shop doing the work put this really tiny filter on the car and I went about switching that out (it couldn't have been half a quart capacity). I went to another O Reilly's (I was in a different city, nothing against the first store) where a helpful counter person went through all the dimensions on all of the filters since he said, and showed us, that part interchange numbers aren't always the same physical size. He found a Purolator that would work and Wix 51085 that I wound up using. It turns out the Wix filter is the same filter that would be used on my 4.7L Dakota, so Mopar parts can still interchange.
