2003 LS - CHARLESW
What a relief
I was sick and tired of wrestling the tiny, short oil filters that are recommended in auto parts stores. You could never get a good grip on them and when you did it would only be able to rotate a fraction of an inch or so. Problem solved with the D2 oil filter

AFE OIL FILTER
This bolt on designed oil filter will make my oil changes easier. You’ll no longer have to be looking for the oil filter tool!

Did not fit
Thread pitch was incorrect, and was too large in diameter

2016 XLT - BoBoy
Beefy
This is way beefier than anticipated, it's expensive but now I understand why. This is a heavy duty, machined, solid piece of billet aluminum oil cap. The logo is etched on so its not rubbing off. I'm having a bit of a fit issue that I'll address with AT but the product is sweet, a must have if you are a fan of aFe, or if you simply like top of the line, sturdy components on your rig.

Awesome filters!
Exceptional fit and meets (or better) than OE quality. Looks and performs like OE and so far hasn't let me down. A definite recommendation for 2.7L F150 Owners. !!

Great Filter
Seems to work exceptionally well. I like to add seafoam to my engine oil crankcase and run the vehicle before I change the oil to free up any sludge or particles, before I add new oil and put on this new filter. Seems to keep my engine oil much cleaner trapping more debris. Also very convenient to put on and take off with the socket attachment.
