Napa gets my plugs for me. They are the normal BKR7E plugs and have the removable tip. You could go for the heat range 9 if they are available, but most only come in the 12 or 10mm thread for motorcycles. In which case you can get a cool set of thread inserts and either thread them into your head, or super-threadlock them onto the plugs so they fit in your head.

Then the CBR coils will work. Just keep in mind they have built in igniters, so you will need an MSD DIS or equiv to work them.

Apparently I should stop sending Dan Martin to get my plugs. So everyone around has these available it seems. I'll have to hunt down a set later. For now I've modified some BKR7E's with no removable tip to work.

12 or 10mm thread pitch, or 12 or 10mm shaft diameter? I'm talking about a threaded shaft that's maybe 2mm in diameter.

I don't think you have the right idea. The threaded portion I'm talking about is on the other side of the plug. Not the side that threads in to the block.

I've been running CBR coils for over a year now N/A. I'm aware of how to get them working. =]

No no no. You misunderstood. The small end (for the coil pack) is removable on most NGK plugs. ALL plugs over 7 should have the removable tip.

On the end that goes into the block: sometimes it is hard to find one that is the correct size for our motor (14mm). In this case you can take the 12mm plug and put a thread insert on it so it will fit in the 14mm hole in the head.

That way you can run heat range 9

I'm almost positive NGK has stopped making plugs with removable tips. Can't find any anywhere. Sifted through boxes and boxes of plugs behind the counter at a store and found nada.

Bosch consistently offers removable tips still, so I went hunting for a part number that will work for me. I found the number comparable in heat range to the NGK-7 which is "6". Factory heat range for Bosch plug for our N/A engines is 8. Two steps colder (lower numbers are colder for American companies and higher for Japanese companies usually) from 8 is 6. By the way, here's the site I used to mostly decode the various brand's part numbers. It also has tons of fun info so it's a good read (Mitsubishi 3000GT centric but tons of good general info).

FR8DCX+ is factory. FR6DCX+ is what I need (in copper).

I also used www.sparkplugs.com to find other cars that run this colder plug from the factory so I can just show up at a local place and say "I have a 1998 Toyota Supra Twin Turbo I need plugs for" and avoid dealing with the madness.

List of factory cars with plug sizes and heat ranges comparable to what I'm looking for (cool cars to pretend you own marked in bold):

Went to Pep Boys and asked for plugs for a 2004 Honda S2000. They were one heat range too hot. Damn.
Same thing for the Turbo Supra.

Nothing behind the counter was in heat range "6" for Bosch.

Time to order from www.sparkplugs.com.

Facebook album permalink (in case the images don't show up in the future).

This was my old, temporary solution.



And for those who kept telling me every NGK plug had a removable tip, this is what happens when you try to unscrew one that doesn't.

lol ben you crack me up. So you tried to remove it anyway huh? lmao.

Always a great learning experience!

I guess you are going to have to use motorcycle plugs.
