No news is good news. The waviness on the crimp was me probing it with a pick to make sure it was crimped tightly over the entire length. It was. These filters are ridiculous overkill for me changing at the OLM (5600 miles this time) on the SRT. But they only add about $7 to the cost of an OCI compared to an Ultra. I'm sticking to the OLM while under warranty. At least in my experience, these are the Bugatti Veyron of oil filters- Champion-built, wire-backed synthetic, and pretty much identical to what they build for Amsoil and others. About $14 including tax at Pep Boys. Oil was M1 0w40 again.

Dad and I used to do that back in the 60s and early 70s all the time, then I got in the habit of a filter every change. These filters could obviously go the distance... but at $14 its still pretty cheap insurance. Running filters for a double OCI is all great... unless you happen to get a defective filter and rack up 15,000 miles on un-filtered or partially-filtered oil (I'm thinking about all the torn Fram Orange, E-core, and Purolator Classic pictures I've seen here over the years.) That's actually something to really like about cartridge filters- you get to see the element before you install it instead of just afterward.

440 Magnum, I see you are a Mopar fan. Nice. Do you use the Royal Purple oil and filters in all your cars? I saw a video a couple years ago when one of them hot rod shows went to the Champ Labs factory for Royal Purple. It was cool. And they look very stout.

With a car like an SRT-8 392, I would go for the peace-of-mind overkill every day! Nice car!

These are nice oil filters...Royal Purple oil filters are the only oil filters we use in our shop. We have cut a few open at 8,000 and 10,000 miles and they looked great just like in the picture.

Dome end. And yes, it mounts dome-down on the 392.

I've been using the Fram Ultra on a couple, also. I used P1 for years but now its RP and Fram Ultra.

Yep very nice. The RP does use the finest media available but only a single layer compared to the FU dual layer, which gives it a higher capacity (obviously you don't need it) Are these 99% efficient like Ultras?

Have you ever considered running the RP longer? I think it would do great at double that interval.
