I was going to buy some NGK B6ES-11 spark plugs but none of the local parts stores had them on-site. Searching around the internet I found that NAPA sells a "Standard Nickel 7910" for the application but doesn't list the B6ES-11 number. A little more Googling and I see that NGK.com has 7910 as stock number but B6ES-11 as the part number.

This might be common knowledge but I thought it was interesting. Did "Standard Nickel" buy the NGK brand name? It's not clear to me what's going on here.

Does "standard nickel" refer to the finish?

It probably does. I just threw some random thoughts out. You wouldn't know it was NGK, on the first NAPA search page, "Standard Nickel" is the big print.

NGK used to be a big name top brand, but they don't seem to be so hot any more. The auto parts stores don't have them in stock, or they have to special order them. Even on the NAPA site, you can't tell if it's a B6ES-11. Thought some people might be interested for future reference.

thanks. I just figured out that that site is actually a front for www.sparkplugs.com. The disclaimer is at the top of the page.

Here's the real NGK site - http://www.ngksparkplugs.com/index.asp Same stock numbers though.

-11 is a .43 gap. I thought .35 is the factory call out. That's why the standard plug is BP6ES or BPR6ES

You are right, Nissan went to the -11, wide-gap plugs in 1977, presumably to match a stronger ignition system. My ignition system is modified from the original 1976 specs. And I should run the resistor plugs (BR instead of just , to go with my resistor wires, to avoid electrical noise problems with my EFI system and ignition.

My original post is more about what's going on with the highly popular NGK spark plugs. In today's auto parts stores most counter people won't know what a BR6ES or BR6ES-11 plug is. They might not even know the NGK brand. Knowing that NAPA part number 7910 = NGK B6ES-11 or NAPA 3824 = NGK BR6ES-11 might help someone out. Most store's systems can't find the NGK part number, they have to look in a separate paper cross-reference book, if they can find it.

Even on MSA's web site, you can't tell what NGK part you're getting, only that the plug they have listed is for your year and model.

I usually get BCPR6E-11 or part number 5632. Most places carry them as they are a common Honda plug. They are the larger gap (1.1) and by dropping the S (for standard tip) you get a V groove plug. They only ohter major difference is that it is the smaller socket size (that's what the "C" stands for). Down here in Tampa, Advance Auto carries them in stock.

I haven't had any problem getting the stock plugs locally. It seems like the last two times I bought them either Advance Auto, or O'Reilly had them in stock.
