Best thing that you can do is send a sample of your oil to a lab. I know we all think bigger is better, but the Ram engineers get the big bucks to figure it out. Here is a test of a sample at my first 5,000 mile initial dealer oil change. They tried to get me to go to 10,000 miles, btw. Ok it's an EcoDiesel, but, I've always done this with my previous hemis. 650,000 trouble free hemi miles. The labs can catch a problem before it gets bad. At least before you go to a bigger filter, see how the stock one is doing.
Yeah they went to electric power steering in 2013 on the 1500s, and the rack took up space under the oil filter so they went to a smaller filter for the 5.7s. The big filters still fit, and are what I use, but I am not sure if the small filter is just what they went to for all the Hemis, or if the 6.4s get a bigger one.
The Coyote V8 in the F150s takes more oil (7.7 qt) than the Hemis do (6.4 and 5.7 both take 7 quarts), because its DOHC and holds a lot of oil in the heads
i recently installed the srt filter. fits on the truck with no clearance issues. it's supposed to be a nicer filter than the recommended standard filter. amazon currently sells it for $11.80 Mopar #5038041AA
Thks guys that is what I was wondering, in the old days we did that all the time. My old 440 Challenger could use long or short filter, always used long, but the Ram filter was even smaller than these.
I agree the filter is pretty small on my 6.4 Ram. I just changed the oil for the first time today in my new Challenger that has a SRT 6.4 and the filter is larger than my trucks filter. On the Challenger I upgraded to the SRT filter SteelHorseCowboy mentioned above.
I honestly don't know if the larger filter will fit my truck. I need to be a contortionist to remove and replace it. The Challenger is super easy to reach the filter. It was actually the easiest, cleanest oil change I've done in awhile.
