So I've been using stock NGKs in my 80 GS SA 12A stockport. I've got a better
ignition system cobbled together and it has proven very reliable and powerful
compared to the stock or a 2GDFIS that I had before. I call it TFIDFIS only
because it uses some Ford TFI truck coils and GM HEIs for the ignitors. I run
leading only with no trailing and it can start my engine even when flooded.

I have a discussion on the other forum for that so I won't go into it here in
detail. Maybe I'll pull it over and post it here if theres interest.

I'm thinking I can get a bit more of an edge out of a better spark plug next time
I change em. I used to hear that 2G plugs were the best but now I understand
that maybe Rx8 plugs are actually the best. I'd loved to see some folks on here
weigh in and discuss it. I haven't made up my mind yet but I'd love to see if
anyone has numbers that can prove one plug is better than some other.
