Great replacement filters
I’m onto round 2, almost due for round three of filter and oil changes on my eco diesel JL and so far these have worked great because i refuse to pay $50 for just an oil filter. No oil pressure issues with the oil filters and fuel filters prime and work as they should.

Oil pressure drop
Once the engine warms up, the oil pressure drops enough to trigger the check engine light every time it dips below the threshold. I decided to try an aftermarket oil filter, but it looks like I’ll be switching back to the pricey OEM one after all.

Perfect OEM replacement
An amazing alternative to the expensive OEM filter. Works just as well if not better.
