I want to change the plugs in my 98' z28 (almost 70K miles and dont know when the last time they were changed) what do you all recomend, and also what about wires?

 

Are you staying N/A? If so, NGK TR55

Are you spraying or boosting now or in the near future? If so, NGK TR6

Those are the only two plugs you will ever need in an LS1

 

yea i was just about to post and say i want to get like a 100 shot for it, what about wires fot it? i was going to go with MSD

another question...the TR6 that you mentioned for spray would be a colder plug i think, so will it hurt my peformance of everyday driveing with the colder plug

 

MSD is good, but so are others.

 

Dont forget antiseize to put on those plug threads. Think about the plug wires...they are only 6" long if that...the stockers are just fine...if you replace them its more or less just for looks and not for performance. But if they are really old and worn out you may want a new set. MSD's are my pick.

 

I am running NGK TR55's, and MSD Superconductor wires.

 

Are MSD coil packs any good for performance? Or is there something better?

 

stock coils are more than adequate for even h/c motors.

i like the taylor spiro-pro wires, less $$ than MSD and are just as good.

 

 

Stick with stock wires unless one of yours is damaged...they work just fine.

 

Nope, you'll be fine. Mine drives on the street a few times a week with those plugs, and I typically don't spray on the street

Stock coils are perfectly fine. I rarley see those changed for any real reason (outside of if one goes bad)

Stock wires are fine too, but if you want to replace them just to be sure, go for it. I replaced mine at around 45k for the hell of it, since I was doing plugs. That and they matched my engine bay better

 

which tr55 plug??? i went to advance auto to get some and they had like 3-4 different ones that all varied in price

 

The cheapest ones. Go to the last post on this page;
