Spark Plugs

holla, holla e'erbody.... i have a '99 3.4L V6, can anyone tell me the best spark plugs they're using on this engine to get the best performance/ horsepower??? Please include which cables are best too :thumbsup:

hey i have ngk irdium plugs and msd 8mm wires and i love em, u wont be able to notch that big of difference in performance i think my car run smoother than i t did but thats as much as i can say ive heard that u dont wont the bosch platuim 4 plugs peeps have had some problems with them but thats what i have heard

I am using the Denso Iridium plugs with MSD wires.

Rule of thumb is same plugs as teh make of the car so some american ones. And the copper ones burn the hottest, but don't last as long. As for wires just about any 8mm wire should be good.

Bosch Titanium series are pretty good too.

^I'm using Bosch as well... and I'm putting in the MSD wires when I get a chance!!!

Don't expect a big horsepower boost with new plugs. LOL

I run the NGK Platinum series by the way, they work. Nothin special.

Yeah, really...at best all you'd do is regain horsepower that you've lost since whatever plugs you've got were new.
