I did a search for a thread I read awhile back, but can't find it anymore.

I'm looking for the part number for the iridium plug from NGK that you can order from www.sparkplug.com and it's not the expensive one, it was like 8-15bucks a piece.

Thanks in advance for any forum member that can provide this info.

 

BR10EIX (and probably BR9EIX, etc.). However, I recommend the B10EGV plug instead. Search for BR10EIX and you will find people (including me) that aren't happy with them and went back to the B*EGV series. Also, I have posted heat range "10" plug numbers here. You might want hotter plugs depending on your mods. Make your own heat range choice before ordering.

I'm in for only about 300 mile and one day on the dyno, and so far so good on the BR10EIX plugs. To hedge my bet, I do have a full set of B10EGVs in waiting in backup.

 

Seeing how small the opening is for the trailing plug to fire into the chamber, do these plugs have the 4 prongs like the NGK or does it have the L electrode that comes up and over. I know the website has pictures, just making sure all are like what's pictures when you plug in the part numbers Max gave us.

Tim, the BR*EIX plugs will have a standard electrode, not the flat-face design of the stock BUR*EQ plugs. There are lots of photos of spark plugs at dis1's website, www.silverbulletrx7.com , a thread on here https://www.rx7club.com/3rd-generation-specific-1993-2002-16/post-your-spark-plug-photos-here-417119/ , and at www.sparkplugs.com if you search by part number, and click "more info"
