FU: Car issues
#11
So what was wrong with the plugs? Were they defective or did you install the wrong heat range plug, or ? I would think that if you used the correctly specified plug for your engine it would work (unless the instructions called for a higher output coil, different plug wires or the like.

Edit: I just looked at their website and the technology page sounds like a big pile of psychobabble bullshit. Just based on reading that stuff I wouldn't touch their plugs with a 10 foot pole.

The mechanic explained to me that the rest of the stock parts either couldn't handle the amount of spark or couldn't deliver enough juice to the plugs, causing them to possibly not fire all the time. Not really sure. All we know is the stock ones work perfect and the car has zero issues. This of course, a $10 fix after I've spent 30x that in trying to track down the problem.

too high internal resistance, or too great a spark gap for a weak coil. (or both) If you have a very high voltage coil with good wires, you can run up to a 1/10th of an inch gap.

Hey, didn't one of us suggest looking at the spark plugs? Why yes, I think so ... but I can see why that wouldn't have been top of list given that they were new ... glad you got the car fixed.

You can get bad plugs right out of the box. If you drop a plug on a hard surface, it is possible to crack the carbon resistor core. Someone at my store dropped a case of Champion plugs, and about 1/4 ended up bad. Lots of pissed off customers. We had several cases from the same lot, and the rest were fine, so it wasn't likely a manufacturing issue.

The real high end plugs ship with a cap or protector over the business end just for that reason.

From your original post I couldn't tell for sure if you replaced the spark plug wires which don't last as long as modern spark plugs thanks to electronic ignitions.

The spark plugs looked just fine. All uniform gap and color. So that in itself passed the test. On a whim we put a new set of stocks in and that fixed it.
