Spark plugs

That does support the reason why you can "turn off" the Ion knock retard system using a SEST. When I first saw that, I wondered why anyone would WANT to turn off knock retard. Well that is the reason. Radical engine modifications to compression ratio or types of fuels would certainly require a different software trigger point. My guess would be for those of you who have made dramatic changes to the engine, to either turn off the feature or deep six the Ion coil pack.

Steve... Sorry about the plugs. R&D does not come cheap!

Yah I know but (EDITEDDDDD), Autolites are about $1.50 ea.
How about the price of thos iridium NGKs you bought.

They were like $34.86 for (4) shipped. Like $8.50 each. That's actually cheap for the Iridium model.

I paid over $400 for a led tail light today but surfed the net for an hour looking for the best price on 4 plugs.? Makes no sense.
