As for the plugs not being worth the cost, you might be right. The plugs do provide better power....so if that was the only difference, it would be worth it. I would love it if there were better gas mileage.

Unfortunately, without detailed mileage logs we cannot trust any findings that you present. There are simply too many variables. I encourage you to start logging at one of the free sites that offers it such as GasSavers.org or CleanMPG.com.

And do you realize that you just came into a fuel economy forum and said that getting MPG really doesn't matter as long as you get more power?
