Are these the same as the E-3 plug that is so popular in American racing circles?

I agree these are street plugs that will last a long time they are good. If you index the plugs so the gaps point at the exhaust valve and change daily, you want somethin different.

Did you mean annually?

And, indexing our 12 plugs seems amazingly ****; for our platform anyway IMO. Perhaps you were referencing the NHRA racers.

indexing plugs is so much work that i would bet it has never ever been done to a m112 engine, it requires an enormous amount of money/time/effort

Takes about 10 minutes for a SBC & was the whole point of the angle plug heads. OTOH the Bosch plugs are perfect for my purposes and may have been being just a teensy bit satirical.
