JL Performance’s Ribbon Delete eliminates a ribbon that comes into the Intake Manifold stock. Obstructing the entrance of air from the supercharger into the engine drastically. Eliminating this Ribbon, the engine boost’s pressure increases between 1-2 lbs. of boost in high RPMs. Allowing an increase in MPH and acceleration significantly. With this kit you have a pluck and play Vacuum Line 1/8 MPT ready to connect to any Blow-off Valve, Fuel Regulator Kit or other accessories.
