Fits Cayman & Boxster 987/987.2 (2006-12)

Fits Boxster & Cayman 981 (2013-16)

If your Porsche Cayman or Boxster is going to make additional horsepower and torque, its engine needs to be able to digest a larger volume of air.  One of the most purchased upgrades for these cars is the IPD Competition Plenum mated to this larger 82mm throttle body.  The existing 74mm version is replaced with this larger diameter Bosch unit that is standard on all 3.8L Porsche engines.

3.5" intake was designed to increase power and torque while scavenging fresh ambient air from outside the engine bay.

Improve intake air flow by replacing the factory 74mm throttle body and plastic "T" style design plenum with a more efficient, cast aluminum "Y" design plenum and 82mm GT3 throttle body.
