pulse plugs?

Recommended Posts

I'd be worried about the pulse plugs going bad faster than regular spark plugs do, considering the immense size of the "pulse" they make.

Other than that, yes, I would like to have the option to tune my car for better fuel efficiency (while potentially getting more power as a side effect).

I'd be worried about preignition. By their own claim, Pulse plugs ignite faster, further and with more force than standard plugs. Without some timing adjustments, that's a good way to get engine knock.

sounds like another unnecessary "super performance" spark plug, which probably won't really give any better results than a good spark plug. At $25/plug, that's an expensive experiment to take. Reminds me of those Bosch +4 platinum plugs. They brag about all the power, but at least in the S-Series, they generally just cause misfires and power loss.
