Cervini's created this complete performance package to allow users of its '67 Ram Air Hood to give their S197 a fully-functional ram air system that, when combined with their performance tune, boosts the engine's horsepower and torque substantially. Each kit includes a specifically designed Cervini's '67 Ram Air Kit and an SCT X-Calibrator 3 Handheld Tuner that is preprogrammed with a Cervini's tune that takes into account the more efficient airflow of the ram air kit. Cervini's performance package fits 2005-2009 Mustang GT / V6 models that have an existing Cervini's '67 Ram Air Hood.
