No speed increase from the NGK but no more fuel scent coming from the exhaust and the fuel needle takes longer to drop so I'm sure that im getting better gas mileage.
I have seen a lot of arguing about whether you should or shouldn't gap iridium plugs. Some say the iridium coating is so thin that the feeler gauge will damage or scrape it off.
Well, I decided to get some more factual info, so here is a direct reply from an NGK technician:
The coating is not the issue when checking the gap but rather the iridium being such a hard material it is brittle and snap off if gapped improperly. When gapping you do not want to apply any pressure or prying force to the fine wire center electrode or insulator or it can be broken and is not warranted. You want to adjust the plug only from the ground electrode. Sliding a tool across the iridium electrode will not damage it though as long as excess pressure is not applied. I am also including a photo of the proper way to gap the plugs. Thanks.

That was a trick question.
Spark plugs come pre gapped.
NGK is OEM BTW.ZeroOne wrote:
