hi guys i am looking at doing tune up plugs and wires and cap and rotor my question is what are some good options for spark plugs? let me tell you about the truck i have a 1998 K2500 5.7L it is not a dayley driver i typically only use the truck for pulling trailers or when i go up north with that is there a better plug fot towing than the stock acdelco i beleve i have NGK TR55 in the truck know anny sugestions on what plugs i should use would be great thanks

 

anny sugestions guys?

 

you cant go wrong with AC Delco rapid fires

 

ac delco all the way and put delco plug wires too

 

if u put any thing beside ac delco ur trucks gann runn like crap. ac delco is made for chevys to perform at ther peek cant go rong with all acdelco

 

Another vote for the AC Delco plugs...happily running Taylor wires though.

 

Damn, did i miss the memo on support ac delco? lol i say TR55 on the plugs and whatever the factory GM wires,cap/rotor are.

 

Apparently the starter won't engage unless there are AcDelco spark plugs in the motor. Something to do with having the proper voltage resistance running through the block

 

Ngk, autolite or ac's..

 

so thats my ******* problem, damn it
