What does everybody recommend to do on a 100k tune up? i was planning plugs, oil of course and fuel filter, anything else i should worry about? And what are some good bolt on performance upgrades besides a supercharger? not sure if i wanna throw a programmer on my truck just yet.

 

IF the oil change was due, I would change it whenever that mileage came up.

 

The good news here for the 6.2L is no traditional fuel filter to change. The fuel filter is part of the fuel pump assembly and inside the tank.

The spark plugs should be changed at 97,500. Besides that...most changes will be fluids. If not changing them, at least checking fill levels.

Mods...hmmm...not many IMHO. Good luck with it!

my truck hit 100k yesterday so it is over due on the plugs lol ill be doing all this next week, ill also put one of them nice rear aluminum factory diff covers on it, anyone got a part number? might make it easier for me lol and what are the best plugs to use in these engines? this is in a super duty btw thought about using motorcraft everything

 

Don't forget...these 6.2L engines run with 2 plugs per cylinder. Also...YES...Motorcraft everything makes sense to me.
