So with my recent changes and wanting to run a healthy dose of nitrous, I started doing some research on spark plugs. I got a buddy who does a lot of tuning on very high horsepower race cars using nitrous and the different forms of boost who kept saying it just doesn't make since that people recommend using a projected tip plug for this.
So I called NGK. I told the guy my plans and we discussed spark plugs. He said, "I'll put it to ya like this partner. Using a projected tip plug with nitrous is like sticking your arm in a fire, you're gonna get burned." I kinda laughed, but it made since. He was pretty amazed at the fact that so many people use and recommend the tr6 plug for use with nitrous and boost. The guy was very helpful and gave me a list of non projected tip plugs to use with out motors
For those of you who want a 6 heat range plug
BR6EF part #3177
BR7EF part #3346
B8EFS part #1049
B9EFS part #1085
Now for those who are thinking this guy is just trying to make the company more money by selling me a more expensive plug, not the case. These are the same price as a good ol tr55 or tr6. I've been driving around on the br7ef for a few days now and notice no ill effects, no bad gas mileage, no performance loss, just piece of mind. You can pick these up at your local parts store or I noticed our sponsor Nitrous Outlet has them as well. Just thought I'd share.
