Are msd wires worth the money? I was jw how much diff 8.5 wires made over stock? Also would you recommend ngk tr6 plugs, or stay with stock. Im starting to do some upgrades and gettin a tune, or if anyone knows of a better plug than the acdelco stockers let me know. If anyone has any advice please tell me.

Thanks,
Derek

 

Stay wit the stock plugs for sure, GM has put a lot of time and money into making their ignition equipement last for the 60,000 mile service window.

Gm plugs for sure. I really cant see teh 8.5's doing much since they are so short on the GEN 3 engines, unless you are running 8 super hot coils or a magneto, teh stockers are quite good.

Put all that money into a tune, and get an improvement you can notice. (unless you allready have one)

peace
