from that website

"As you can see, our heat rating number goes up as speed, load and temperature go up. In other words, higher numbers are colder plugs. A colder plug simply has a better ability to cool itself."

So I guess you were right all the time. BCPR7e-11, will be a colder plug. Now when where and how much colder you need it, i'm not sure, I'll keep checking

I found this, it shows a few different ngk's BCPR7 plugs

and here they have the bcpr7e spark plugs from $2.00 each

I'm still looking at how and were to find them locally. I know I bought a set of these from a local racing shop about 2 years ago.

well, if that is the right part #, take it to any auto parts store, and if they don't have em in stock, they can prolly get them overnight

Just go to an universal parts store, I'm sure they've got what you need.

Anyway, an easy way to check if you really get colder plugs is to measure the dept of the hole around the center of the plug. If it is a colder plug there will be more metal around the core (to conduct heat away) and the hole will be less deep.

I guess I was wrong. I always thought it was lower to go colder. Good thing I never used colder plugs(or tried to anyways). I can't believe the parts store can't order them for you. Checker can order anything you need and have it within a day or two out here. I think they are just being *****. Go somewhere else.
