The 986 Boxster Non-S 2.7L Plenum provides impressive net performance gains throughout both power bands, especially in the midrange where we all want and enjoy it most. The Boxster Plenum and upgraded 74mm (from 68mm) throttle body package is an absolute must for enthusiasts looking to elevate the driving experience of their vehicle to the next level. Power gains are 12+ wheel HP and 12+ wheel TQ with net gains being realized from launch to redline. This is the perfect upgrade for both stock and modified Boxsters with no ECU modifications necessary.
 
Custom IPD Silicone hose is included with the purchase of Plenum.
