Hey guys I need your help again. I am going to to a tune up on my 97 Z28
6-speed. The cap and rotor was $250 How often does this need to be changed out. Also bosch platinum plugs +4 were $7 each, is this what I should run?

 

You can buy a complete opti for less than $250! Don't use Bosch plugs. ACDelco, NGK or Autolite have better track records on the LT1.

 

Hey man where can I buy a complete opti for that price?

 

a 95+ opti (complete) used to be $180 from Dal

 

Do a search for "Jason Cromer" of "Dal Slabaugh". Shoebox also has a link to cheap GM parts sources on his Tech Pages.

I think I'd change the wires and plugs first, and see if that cures the problem. I'd save the opti until last, unless you know for sure it's bad.

 

You guys are awesome thanks, God bless
