Nice plug, sometimes hard to find though. You can get very close with a
lambda sensor, but it's still best to read the plugs for final, final. I
bought one of those LED lambda gauges, and it shows good mixture when I'm
still a little rich. Your mileage may vary.

I use a lambda sensor for testing the mixture while running. I measure the
voltage output of that sensor with a simple digital volt meter.
As spark plug I use the Bosch Super 4 WR 78 G at my TR4 engine. Very nice
burn through, good stuff for racing. Reliable.
