this filter looks extremely small. the specs do not list the 3.5EB either. i will just stick with the Motocraft filter.

I run the same filter and royal Purple oil.Royal Purple PN: 20-500 also replaces Motorcraft PN: FL-500S and fits the HO 3.5L ecoboost.
This is the filter I’ve been running since seeing the size difference between the OEM filter that came on the truck from the factory and the Motorcraft.

Seriously WHAT IS THAT. And how could it possibly be related to the oil filter though?I’m a Pennzoil Ultra Platinum guy but have been considering trying something new since two different dealers have told me the rattle, tick, grind symposium I hear with every cold start is “normal, within spec.”
Maybe I just need a new flavor of snake oil.

Wondering if you ever found a solution?Anyone else using the Ford performance filter?
Have read somewhere that the (filter specified in the manual) FL-500s bypass valve is set to a different pressure than the 820 series.
Really would like to buy a premium filter to use but am concerned the cm-6731-fl820 is not appropriate for our trucks.
If it IS... I’m ready to place an order.

It's the only filter I have ever put in my truck, if it doesn't fit that's news to me.Wondering if you ever found a solution?
I called Ford Performance and they said CM-6731-FL820 is the correct filter but that their isn't enough space for it?
