i havent changed my sparkplugs or even looked at them since i bought my car last october but i kind of want to. i have a couple questions though...

i was thinking about getting some sweet iridium or platinum spark plugs from bosch or something. is there anything bad that could happen from putting those sweeter plugs into my car since it is basically bone stock(getting e-prom soon) or will the better plugs do nothing but help?

which kind of plugs should i go with?

and finally, how much of a pain in the **** is it gonna be to change them. i helped my roomate do it on his lt1 and it was a big pain. any tips or tricks for me to make it easier.

 

First of all, fourth-gens have the engine mounted further back for weight balance. This makes it a pain to reach the plugs, yours should be easy to reach, especially if it has the stock exhaust manifolds.

From what I know, AC Delco plugs are your best bet, the fancy stuff doesn't run as well in our engines, they are more for higher end Jap and Euro engines.

 

I agree, save your money and put ACDelco, Autolite, or Champion in. Alot of people have a personal preferance, I like Champion.

 

Get a set of NGK 7's. I run them in my daily driver and the 9's in the "race" car. 7's are a little hotter so they tend to burn off all the carbon that builds up during stop and go traffic.

 

Here are a couple threads that span some info that may help.

Generally you go with the rare metal electgrodes for durability. If you are going to regularly maintain the vehicle, I'd just spring for some copper cored plugs from AC, Bosch, etc.

IIRC RB had a really good write up a while ago, couldn't find it. There was a good write up I had done some years ago as well but I couldn't find that either.

 

thanks a lot for the advice guys. ive always had good luck with AC delco stuff so maybe ill just stick with that.
