    Best spark plugs?

    What is the consensus as to what plugs are best for a stock M20.

    NGK ZGR5A plugs.
    The car makes it possible, but the driver makes it happen.

            Just get NGK ZGR5A and be done with it.

              I suggest just standard copper plugs from Bosch or NGK. OEM equivalents.

                another +1 for NGK. I use BPR6ES in my stroker with D585 coils.
