Stock NGK plugs are gapped at .028, above .035 on the stock coils and ignition typically will result in a loss of power.

Everyone is allowed one "Newb" question. We were all there once.

Now don't let me catch you asking about a more agressive camshaft around these parts.

You can't re-gap the stock NGK spark plugs. They are multi ground.

The Denso and NGK Iridium plugs can be re-gapped:

Well I have had my RX7 for three years. I knew you couldn't gap the stock ones, there is no way, but I have never seen a Denso or NGK Iridium for my car. Do those plugs really make a difference where it is worth spending all the money for them?

If you're having a problem with excessive unburnt fuel, then they might be an option... The idea behind Iridium plugs is to get the most out of your gas mileage for racing due to the more complete burn... Not recommended for street vehicles...
