The more cold air you can get to the airbox the better, Supercharged or not! That's what it does. It is not Ram Air. The cat has the ram air cold intake in the park lamp. But as stated by Dodge the supercharger use's a lot of air.Wouldn't the shaker be literally pointless sitting on a supercharger? Personally, the idea of a "shaker edition" turns my stomach. It was a single option back in the day and didn't need silly embroidery. What's next? The Magnum 500 edition? Just offer the shaker as a stand alone option on the non supercharged cars and don't make it silly.
