What is the pressure between the spark plug gap and ground electrode?

between the spark plug gap (center electrode and ground electrode). 2) Pressure in the combustion chamber at time of spark discharge – Depends on compression and aspiration of the engine. High compression engines and engines with forced induction have higher combustion chamber pressures at time of spark discharge.

What’s the gap between spark plugs on a Mazda 3?

On the old plugs at rpms above 3,000 I noticed the spark was being blown out. Here is why: Plug gap on the factory standard plugs. I installed Autolight iridium plugs at .045 gap (had to regap the plugs) and found under a dyno load testing with a emission and scope analyser, emission output was much better with a narrower gap than stock.
