Here are the last 6 filters from our 07 GMC Yukon Denali w/6.2L all aluminum L92. All are Fram Ultras except the 1st one. 3 filters have carbon in the bottom of the pleats and 3 don't, in no particular order?
In Dec of 2019 a plastic heater hose fitting broke. Engine got hot for a minute or two. I didn't change the oil and filter for another 4k miles. I should have changed it immediately.
Interesting is the color of the 2 filter pleats after it got hot.
