Spark Plugs

[MBillings]

I have used Champion N6YC spark plugs in my Lola T644 Formula Ford since I bought it. I'm considering using a different brand. What plugs are other autocrossers using?

thanks,
Mike

Mike,

Don't know how credible I am anymore but with the iron head I've always believed that a street heat range plug is best for autocross. Due to a funny "quality story" with a set of Champions for my tow vehicle I switched to NGK GR5GP's this winter in the FF. So far they "behave" well with no miss fires's etc.
