If you're over driving your factory or aftermarket Heartbeat 2300 supercharger, your 4" or even 4.5" intake will cause a parasitic loss and increased IAT2 temps when trying to inhale the air in the higher RPM range. By going to a larger intake tube, the air can move more freely into the throttlebody and snout to be compressed inside the supercharger.
