Not sure entirely, Wix does seem to favor the combo for filters to the masses, yet on clones of certain still up to date filters (like the Motorcraft FL-910s and FL-400s, Silver 31348 and 31516) they use a Motorcraft style thread end bypass. So OEM style seems to have something to do with it at least in part.

There are not many if any current vehicles that actually spec an FL1A (I don't think Ford has produced a vehicle that spec'd it since the 90's) so the equivalent there gets the combo valve.

I have found the combo valve filters to perform great in actual use, but I have still come to favor the one pictured here.

This Silver has a similar bypass valve as the Napa Golds along with the same coil spring.

You’re right, jeepman3071! Pairing a quality filter with a quality oil is an excellent way to keep your engine in top condition. If you are considering Pennzoil for your next motor oil change, we recommend Pennzoil Ultra Platinum or Pennzoil Platinum. Additionally, depending on the mileage of your Jeep 4.0L, we now offer a full synthetic high mileage motor oil, Pennzoil Platinum High Mileage. Hope this info helps! – The Pennzoil Team

Thanks. I use Pennzoil synthetic products in the other vehicles in our family, but this 4.0 engine seems to run quietest on the Yellow Bottle Conventional. I run it in two other 4.0 engines owned by friends with similar results.
