I have to agree as far as the corrosion part of it goes. If the vehicle doesn't get used all that much, I think the brass gets corroded quicker. IMHO

 

oh it got used plunty while it was on there. Alot of people say to use it but I wont again. I'll buy a msd if they make one before I buy a napa one again. Plus our local napa is a rip off I'll drive farther to an Advance before going there

 

I just go with SMP ignition parts. Never had a problem. Even the wires are 7mm and routed they way they were from the factory not according to the TSB. I'm afraid to change the routing! LOL

Only time I had misfire probs was when my plenum gasket was bad and toasted my CC.

 

this is my experience.my plugs,wires,cap and rotor,and coil werent bad. all were stock form. i replaced them with everything above and felt no performance difference,or mpg difference. same with the msd boxes. i have put them on 3 different vehichles and couldnt tell any difference. i wont be putting a msd box on this truck. now if you had a full blown race truck,the msd box might help then. but on a slightly modded motor,on just think they are a waste of money.just my opinion.

 

I agree totally!
