I'd stick with the standard plugs for this motor for now. Maybe you can pick up the turbo button, but continue to use the your stock button until you use up the plugs you have. One more thing to consider is that with turbo plugs, you have a fitment issue with some plugs and need to stick with a certain brand of plug. Also, once the button starts to wear, you may experience more difficulties with sealing the plug when installing a new plug versus the use of a standard plug which uses a copper spacer to seal up the plug with the button. It wont make that much of a difference to a normal racer. I'd save the money for other things and just keep turbo plugs in mind for your next motor.
