I'm getting ready to tune up my 2006 Silverado Z71. It has a 5.3 V8. I'm using A/C Delco Iridiuim plugs, and want to use A/C Delco wire set. On RockAuto.com there are about 4 different sets to choose from, and would like to get a better idea as to which one is the best to go with. My truck is used for normal driving, nothing fancy. Thanks for your help!

 

Normally the price of plug wires goes up as the size of the interior of the wire goes up. 6mm,7mm,8mm. I have used all of them thinking bigger is better. Not really, unless you are hopping up your engine with a cam, HE distributor and coil ect. If you are just doing a routine tune up, I would ask for there OEM replacement wires and save your self some money.
