i know the wires can have an effect on hp output but what should i go with for a cap and rotor? does it matter? i'm gonna do a tune up and get new plugs, wires, cap and rotor, so i'm taking suggestions on all, but my biggest question is the cap and rotor or is there a whole kit i should get? i think it says at the bottom but i have 99 1500 5.9L 4X4

 

All the guys on here say a brass contact cap. Iv'e used them all, and from now on I'll get the cheapeast cap and rotor they have. That's what I have on mine now, and it works great. They usually outlast the spark plugs, and wires 2-1.I think most folks pay for pay for parts they don't need. Is your engine stock ?

 

engines stock for the most part, i do have superchips, cat back exhaust, and cold air intake...just want to do a tune up and want to put (not necessarily the best rated) but the best for our trucks in it. plugs, wires, cap and rotor

 

Stock cap and rotor man, like 28 bucks for both at autozone just becareful changing them out, kinda a b!tch to get to

Edit: i use autolight double plat plugs with 8.1mm wires. the cheap 7mm wires are about 30 bucks which do the samething, i just got the 8.1's because they were onsale at the time and were like 9 bucks more than the 7mm wires

 

I use a Brass terminal cap and rotor from NAPA.
