Competition Plenum 82mm Throttle Body Upgrade

The IPD 81482-3.8 Competition Plenum is engineered to enhance airflow and throttle response for specific Porsche 981 models. Constructed from durable cast aluminum, this plenum features an 82mm throttle body opening, significantly larger than the factory's 74mm. This upgrade, along with the plenum's Y-design, aims to improve intake air flow efficiency. A custom IPD silicone hose is included with the purchase to facilitate installation. This competition plenum is specifically designed for the 981 Cayman GT4 3.8L (2013-2016), as well as the 981 Cayman Base/S/GTS and Boxster S/GTS models within the same year range. It's an upgrade that can potentially yield an additional 20 HP and 15+ ft-lb of torque across the power band.
