Re: 230-250 I6 hei

I use nothing but NGK V-power racing plugs. You can go to their website and cross reference your plugs.
They are usually only about $2 a plug. had real good luck using the .045-.048 gap. When using the MSD 6AL digital seemed to like about .055" gap better.

I figure if they will last in the Fuel Altered on 25% nitro-methane they ought to last on pump gas.
