Your Favorite Tune-up Parts

[Kolt-46]

I'm going to be doing a "tune-up" to the 08 Hoe sooner than later. I want to know your recommendations on which parts to use for the following and what else you'd do to a near 70k Tahoe. I use Royal Purple motor oil and a K&N oil filter.

Injectors
Plugs
Wires

What else am I missing? Flush anything? Change differential or transmission fluid?

Thanks for your input!

Transmission Fluid and Differential Fluids are due @50,000 miles as per GM, i ALWAYS use genuine GM fluid for the differential and trans, if you want the warranty till 100k to be covered in case of a problem.

Plugs i use AC Delco
Wires, Usually dont get done for awhile but if you do them i was always told the genuine GM or AC Delco wires are the best, even on my 06 GTO that has had motor work done i used the stock ones also, no advantage to the after market wires.

Injectors dont get replaced, maybe a cleaning, or a gas tank additive, but thats all.

Just did a tune up myself, AC delco wires and NGK plugs. good ol copper TR5's 1.79 a piece. and like said before, just get some good injector stuff to put in your tank and run some good premium fuel with the additives like shell or whatever.

I appreciate the input. Sounds like the OEM stuff is the way to go.

I prefer Mobil 1 over Royal Purple oil i really never seen a big improvement when I ran it, I sometimes use seafoam in the tank to help clean the injectors.
