I have done a hell of a lot of pulling & racing with this truck. I just make sure the fluid & filter gets changed every 25,000 miles.
I use IH.
If you happen to get an aftermarket with the lid already on it, DO NOT throw away your factory lid. It will cost ya if you go back to OEM filters!
I went back with Motorcrafts. My originals lasted 7 years. I figured if they lasted that long, why not go back with OEM. Plus, they have a 5 year warranty....3 year replacement, and 2 year prorated.
