Sorry, I meant T or L. Sometimes, they print them in small lettering.

Just so you know, I work at an auto parts store. And your chances of getting a person to help you that knows ANYTHING about a rotary, is slim to none. Plus the fact that people coming in for RX-7 plugs happens about once every year or so. There is a good chance you got an old pair of plugs or the wrong ones entirely.

there's indeed a "R" below NGK. If you look on the other side though, there'll be a BUR7EQ & BUR9EQ.

Thats what I thought.. But the ones that had the "R" also had the "T" and "L"
