lately i've been reading up on upgrading the plugs and wires in my 02 ss n/a. after a few articles, some research and a few discussions with the father figure, i was curious if anyone had swapped out there plugs and wires and how big the difference was afterwards or how big it would be. i'm also looking into upgrading the stock igniton coils to the MSD components at the same time but lack the knowledge completely on that subject, Would anyone have anymore advice on these topics? thanks

 

Here's all the knowledge you need. Stock coils and wires are perfectly fine, even for high horsepower uses. The only reason why anyone would swap them is just for looks.

The stock plugs should be changed to something else ONLY IF you are modifying your engine to the point that it requires a colder plug. Other than that, it's really just wasted money.

 

Couldn't have said it any better myself- leave it all stock, or OEM replacement.

Only thing I'd change are the plugs to appropriate heat range coppers on a SC setup, otherwise I'd leave the stock platinums in anything else.

Only reason I changed my wires on my monte to PRJ's, is because I change/check/pull the plugs quite a bit, and the stock wires come apart easier when doing that. But for a car with 100k mile platinum plugs, that shouldn't be an issue- you could just buy new OEM replacement wires when you did your plugs.

 

well i know my plugs are due for the change, but i figured while i'm at it, if i can upgrade the other components then why not, but thanks alot, money saved that can be spent else where

 

what wires do you recommend for autolite 103's?

 

Thats what I've got in my monte (and 104s in my GP)- I use the PRJs on the monte because I pull them so often (reading the plugs, etc), I bet I've pulled the plugs maybe 10 times so far between doing mods/installs and reading the plugs- in my gp I've got OEM replacements because I've only been changing the plugs every ~15k- and the OEM ones held up fine the last couple times I've done it.
