Guys using the GMS Coil Packs in here....

I was talking to Jimmy (Dealerjim) about the height difference an insert could possibly make I remembered that my stock plugs were still laying around on a shelf in the garage. I wanted to compare the height of the stock Motorcraft plug vs the NGK TR6. I think this pic tells the story.

My suggestion would be to make then fit the TR6 and should still slide down on the stock plug enough to make good contact. The vast majority of people that buy the coil packs are not running the stock plugs. The TR6 is the plug most used. If someone has a Denso to compare to the TR6 it would be helpful.

would provide the tolerance relief and still maintain spark integrity.

I got my GMS COP's today. I installed them with some BR7EF's gapped at 0.032. Everything seems to run great. It actually feels smoother and idles better. I only got into boost about 5#'s so I couldn't tell if the spark is going to blow out under higher boost.
The first COP I installed fit just fine. I didn't have to trim it at all. All of the rest of them were too long. I cracked two of them, but the tab didn't break off. They didn't crack bad enough to warrant me returning them or feeling iffy about leaving them installed. I had to trim 6 of them. I preyed the connectors apart, pulled the cable, trimmed off about 1/8", and then re-crimped them. That worked great. They all seated fully and I didn't crack anymore.
Changing the plugs wasn't as bad as I anticipated. It was actually pretty easy. Just a little time consuming. All and all I am pleased with the COP's. Even though I had to trim them a little. I will get out on the road when it warms up a little and see how they perform under full boost.

I've got two questions for you guys since no one is paying any attention to my thread...
1. These are my old spark plugs. How do they look? One of them had oil on it when I pulled it. What does that mean?



2. Will running colder spark plugs in really cold weather increase the chances of fouling them out? I was running TR-6's before and I don't want any problems with the BR7EF's.
