N/A cars should be gapped at .060. Even Wes'* car with almost 260 at the wheels is gapped at .060. The reason for gapping smaller is to resist the higher cylinder pressure of boosted cars (or nitrous) blowing out the spark.

Ahh HA, that makes sence. My original plugs had gotten up to .75 when I changed them. I'm amazed the car ran as good as it did. The plugs where not fouled just gapped way too high.

NGK TR55'* and stant thermostats can be bought at any Advance/Discount auto parts store for pretty cheap... I think I paid 1.69 per TR55, and in the $9.00 range for my 180F T-Stat... Save the charges and get the parts locally if possible..

Ya i just did a tune up on a little escort, the plugs were at .090! Lol i couldn't believe it even moved, but it had a TON more power afterwords. Gap definately at .050-.055. Mines somethin between there and even with the magnavox it works great.

I love the TR55'*... So far better than any of the AC 41-606 plugs from the factory, or the Autolite 606, or most plugs I have used...

I have also used the Rapid Fire 14'* and liked them as well... But for the price I just can't beat the NGK'*...

Do you have an Advance auto parts near you?

How far away is this from you?
496 State Route 3
Plattsburgh, NY 12901-6523
518-566-6173

From the Zip, this is the closest one to you..

I'd say .055 - .060 shouldn't be a large diffrence.... But I'll let our guys hash that one out... I checked my gaps out of the box and they were closer to .055 than they were .060 for whatever reason... I have used them that way in both of my cars with no ill effects...

We have a whole bunch of info on the NGK plugs somewhere...

I think its called " Tech Talk with NGK "
