The FP EVO intake pipe is used to connect the factory MAF to our larger 80mm inlet Flow Advancement Port™ turbochargers for the EVO 4-9 applications.

This pipe retains the function of the recirculation BOV and its position on the intake pipe, as well as the factory crankcase vent.

Remember that running unmodified factory airboxes beyond 350whp can lead to power reducing levels on vacuum in the inlet air pipe and possibly even damage turbochargers if taken to extreme levels.
