find the right spark plug
If you're stepping up to a 200 hit, I hope you AT LEAST have a racetronix hotwire kit installed and hope your fuel system can handle it. Make sure you pull timing and I would go with an 8 plug (B8efs, part #1049). You can drive around with 8s if your tune is right.

i always understood going from a projected to a non is worth a full heat range point. can anyone prove this wrong? does ngk use one heat scale. From what know the TR has it's heat range, the BR has it's heat range. when you go TR to BR its -1 right there.
