I'm a n00b to the forums, but sold parts for about 6 years. I keep reading posts about plugs and which ones to use. I just wanted to let everyone know that Autolite makes Motorcraft plugs and ergo, they are one in the same. They are stamped differently but created identically in every other way. I hope this saves you some $$$ at the parts store where the kid behind the counter tries to sell you the Bosch +4's since it's the highest price he can find. Research: http://www.autolite.com/products/index.html.

Most of the people here have tried to shy away from using Bosch plugs beacuse of high failure rates. I think most people are using Autolite/Motorcraft plugs in their Tauri.

Thanks. I just didn't want members wasting time and/or $$$ on Motorcraft if identical Autolite plug as available, or vice versa. I know AutoZone sells both and Motorcraft are a few cents higher I believe.

I use NGK TR6. They are copper and one heat range colder than stock. But I have used Bosch DP's as well as motorcraft copper plugs, and they have all been good.
I used to always run cooler plugs on hotrods but I have wondered about what the computer would think of a cooler range plug. I may try that on my next change.

Alberto suggested I use them when I had my EEC reflashed. For the Vulcans I'm sure it will help prevent detonation alot. I also put in a 180F thermostat to prevent detonation.

The plug fires just like normal, so the EEC won't know the difference. The colder plugs just have a longer heat sink around the electrode. Copper plugs don't last as long as DP's, but they conduct electricity much better.
