This kit is to blank the OEM holes left in the plastic intake manifold after the removal of the swirl flap system and actuator. Typically no swirl flap system is to be found on the iron block variants. However, you only swap manifolds if you're in striffe
 
Great upgrade and protection to your alloy block N2 motor as the OEM flaps do tend to break and fall inside the motor causing catastrophic damage
 
Kit contains: 
x1 seal kit 
x1 blanking kit (6 blank off plates)
