colder plug part #
Curious what plugs you guys found that are 2 steps colder than stock. I went to the O'Rieley's and they didn't have any NGKs colder than heat range 5.
It's quite possible though that their guys behind the counter were complete idiots. I had to argue with them for a few minutes that the last 2 digits in the spark plug part number were the gap, not the heat range.

thanks for (finally) getting it to me. cuz you know I need it n all.
I done ordered me some ngk zfr7f-11 . They are extended reach heat range 7. Which is the coldest ngk copper plug I could find that would be correct for the miata. They cost about $.25 more/each compared to the bkr7es-11.
