Thanks
engine seemed to run alot smoother and fired up quicker. As for the wires again no real gain in HP. Stockers are actually pretty good although I did change mine too. Just my .02 worth.

Over 50K miles, the plugs are heavily worn and need to be replaced. Any noticeable gain would be bringing you back to stock power levels. The stock gap is 0.060" and after 27K miles, mine were in excess of 0.070". So, you can see there could be a drop in power with those kind of gaps. The stock wires are alright and is dabateable on whether there is a increase in power.

the stock plugs for white as hell on the tip and so were the wires. HP had to go up. i felt a very noticable increase in acceleration.

yes... the original/stock plugs and wires wire burnt out! my question is has anyone dynoed their car b4 and after to see what the gain in hp is? i really don't want to have to pay $$ for a dyno run that's all.. 5? 10rwhp? remember.. plugs were whiter than a ghost lol
