Tune-up parts suggestion...

[SoundZman]

Just picked up this Suburban a couple of months ago with 70K on it. I have no idea how the maintenance stands right now, I know how all the fluids look that's about it. So I decided to just go ahead and due a tuneup on it since it's getting about 13.1mpg around town, seems a little low then when I first got it.

I'm looking for some recommendations on spark plugs, wire sets and any other tuneup parts that you guys have seen results with.

Thanks!

Seafoam first off

Then a set of stock wires will be fine
Plugs many schools of thought kinda like coke vs pepsi Im trying some Denso TT right now and they have been good so far and were inexpensive.

Check out Chevy Parts they shoud have the stock wires delphi and AcDelco and are pretty reasonable

Also check your cooling system see what the levels are and check the antifreeze to see how well its still working
