Went to two different auto part stores to buy the NGK 6994 spark plugs and ask the workers to double check the spark plugs to make sure it was 0.44 for me and surprisingly both time they were not. I understand that iridium spark plugs should be "pregapped" but these were way off at 0.35 to 0.38 ...

How do you you guys gap Iridium spark plugs to 0.44? What tools do your use since the center is so fragile and thin.

 

94

 

Thanks. I picked up a similar tool from Sears.

Car drives a lot better with new iridium plus properly gapped now. The shop that changed my plugs last time didn't even bother to check the gap, it was WAY OFF. All I can say is the plugs are NOT pre-gap like what you see and hear all the time.
