2003 Tahoe tune up suggestions

[Tahoebigdog03]

Hello guys I'm about to do a tune up on my hoe soon she has around 150, 000 miles on it. What are some good spark plugs and wires to go with? Oh while I'm doing the tune up is the anyway to squeeze out anymore horses out of this hoe.
Thanks

Stick with AC Delco!

When I did mine, the consensus was to stick with stock parts. What engine? The 5.3 has one plug that is a whole lot of fun to remove.....wear a glove if you enjoy having skin on your hand (okay, it's not THAT bad, but still a pain).
