Quick question on these plugs - R5671A-7 Hey guys. I usually run BR7EF's in my nitrous setup. I went to a local speed shop and told him I need a non-projected tip number 7 plug. He gives me these NGK R5671A-7 plugs. They look identical to the BR7's, but obviously a different part number. Has anyone used these? Just wondering if I should return them or not, thank you.

That is the most common plug used by BBC guys I know.
If it's the correct heat range, there is nothing to worry about.
I have a bunch of them, but I use a -10.

Also the BR7EF's are tapered seats while the 4091's are gasket seats.
Edit: Just did some reading and my DART heads call for a gasket seat plug at a .750 reach. So it looks like I will be using these

I asked around about resister, non-resister and got ZERO replies.
I also use br10es which is a resister plug and one of my 6 second friends said I shouldn't??
I personally use whatever I can get, I just don't mix them??
I buy 50 or more at a time, so whatever I find I stock up.

The only part that is stock anything is my roof.
Like I said, I did ask around and nobody said which is better, but I do have a data recorder,
and I've never had any strange readings or glitches using a res or non-res plug.
I would probably use a resister plug on something with all the fancy crap you guys have now a days.
I would highly doubt there is any power loss??
