I'm running a Bosch wasted spark coil pack intended for a 2000 era VW 2.0L engine. The factory plug was a BKUR6ET-10 (.040 gap) and that engine had 10.5 compression. Thus the question. Don't get me started on how wasted spark systems wear plug gaps differently depending on coil bank (most use multi-ground electrodes to even the wear).

Yep. When the car makers figured out how to make chambers that didn't invite pre-ignition, they needed to figure out how to light the fire under those kind of pressures. Once they figured that out,  they needed to make plugs that wouldn't burn in half every 20,000 mi.

After they figured that out, we got to a 100,000 mi tuneup interval, meaning that Trixie the Hair Artist could drive her Honda indefinitely without doing anything but fueling it up.

If only they could figure out timing belts, a modern car might run forever.
