Re: Pulstar Spark Plugs
You could run the test with the original plugs, find the weakest cylinder and replace that one with a pulstar and re-run the test to see if anything changes.

Re: Pulstar Spark Plugs
Supposedly that is not a problem. The very intense spark is for a very short duration.
The spark itself is not considered to be the problem, the resultant initial spreading, propagation, of the flame front is. Inital propagation of flame front with standard plug MUST be sideways.
It is my understanding that this has happened in modified cars, and they warn not to use these plugs in modified cars.
And just what might Pulsar's definition of "modified" really mean, manufacturer's firmware year to year changes/revisions, TSBs, etc....??
Is there some thing that can be measured with a scan gauge that can tell me if I have a problem with “hot” pistons or some way of knowing if this will happen before it actually happens?
Your first "warning", if at all, is likely to be years away when the engine is disassembled due to failure and tiny pinholes are discovered in the pistom dome immediately beneath the spark plug anode.
One would think there would be a lot of reports of this happening, because I can’t be the only person who has bought these plugs.
Reports: How many 3-4 year old engines do you suppose get a post-mortem autopsy....??
We will see what happens.
Also, anyone know how much torque to tighten the plugs?
