Yes it was.
I'd definitely follow his recommendation then
for an engine that's pushed.
Do you or have you tried indexing your plugs??
But, for a standard engine normal driver you should be able to screw almost anything into it and not have a problem, SHOULD. I don't think plugs are the issue but I'm sitting in the dark out in the middle of Wisconsin so you should take that into consideration.
The other thing is that like Boxpin I have a coil that will put out more voltage and amperage than a stock coil and we don't burn up plugs. A high output coil is like a garden hose with a nozzle on it. It's not that it puts out more voltage all the time, it's that it CAN when it's needed. Most of the time it's putting out the same voltage as a stock (less expensive) coil. Under extreme conditions
it can supply more if more is needed to jump the gap.
If you are running the stock coil I doubt it's burning out the plugs.
Do you know what a burnt standard plug looks like? I've run into a lot of people who have no idea what the iridium or platinum plugs look like new and they think they are burnt out. I ask because it may be what they are telling you but it may not be what's happening.
Best thing is if you can post a picture. I'm sure there are a couple guys here who can "read" the plug for you. If it is burnt out then we're back to the drawing board but I'd do the rest of the secondary first.
Also if you buy a 5-15 dollar plug with the tiny spike electrode DO NOT use a ramp gapper to check and never adjust it with one. If you do you just scraped off 5-15 dollars of platinum or iridium and you have a 1.29 plug
That coating is less than a hair think.
