Are they worth the cost? Sure, but don't expect to some magic HP increase.
capnsavem said:i gotta ask though... how much more of a difference does iridium plugs make, rather than regular or platinum? and what are the differences? (for exmple, you said a smoother idle).. and are there any possible NEGATIVE effects from upgrading to iridium on a car that isnt heavily moded (just CAI and rear section exhaust)?
