Road Rage......Did you have to change the gap? Were they plug and play?

105,000mi that's unbelievable. seems like perfermance would suffer by then.

Ok, for those ofyou who use copper plugs, what is the part number?

Im' trying to find that out and the only thing that I found close enough was BR7ES or something like that.

The whole idea of Platinum plugs (and Iridium) is longevity without loss of performance.

 

I have recently put in NGK (6564) R5672A-8 copper "V-Power" plugs for my F.I. application. There are gapped down to 0.034" and are 1 heat range colder.

So does the stock plugs provide the best performance regarding horsepower, torque, and fuel efficency?

 

So there is a chance that if we change the plugs, we'll get more hp, & tq.

Got to do some research on this subject. doesn't have to be the S2. wonder if there is dyno somewhere.

Well I guess this is what this thread is about.

Thanks for the info.
