alright trying to finish off my ignition part of the truck, i have msd blaster coil, msd wires, brass cap and rotor. and i now need the msd 6A box, i was wondering whats the best plug that would hold up with this box, was thinking spitfire or ngk . i have reg autolite in there now.

 

I would guess Denso Iridium, but i dont know. Also, are you going to get the direct fit MSD harness?

 

msd harness ??? who makes denso

 

i prob will prob get a harness yeah . anyone else opinion on this

 

i'm using ngk's my truck loves them no problems yet and they have 30,000 on them just a suggestion

 

you remember what part number you used for the plugs

 

its a harness that just plugs in to the factory harness for easy install.
