I thought you did not trust IB dynos?SurferX on Sep/02/02 said:Not if you're stock. You need serious compression or forced induction to actually get anything out of them.
Import Builders did this dyno of Denso Iridiums vs Bosch Platinums. Even on a moderatly modified N/A car making over 200whp, barely any difference. I don't think you have to worry about spending the extra cash on iridiums for a stock 120whp non-vtec motor.
