Anyone replace their coil wires yet?

Anyone make an upgrade or just a OEM replacement set of coil wires?

Various places have aftermarket like MSD wires you can get for your truck. Summit, Jegs, plus check the preferred venders on here.

 

I don't see the need to unless your running higher compression, supercharger, or just feel like changeing them out and have the extra cash to spend.

 

Some might say different.

Nology and JBA make a great set of wires for the NBS trucks.

Didn't have the extra cash to spend, but went with MSD 8.5's for the heck of it...they look cool. The stockers are more than sufficient though.

I used a set of AutoZone replacements. No improvement in power or performance. But it runs better than before.

After 4 years and 80,000 miles, I replaced all the plugs and wires with OE AC Delco parts. Idle's much better (smoother) and seems to be more responsive than before. Then again, how much was the wires vs the plugs is anybody's guess. The plugs looked "OK" for 80,000 miles but they sure were used.
