The IPD Competition 82mm Plenum is a high-flow intake upgrade for 2009–2012 Porsche 987.2 Cayman and Boxster models with the 2.9L or 3.4L engine. Designed to increase intake airflow and improve distribution into the factory intake manifold, this plenum replaces the factory unit while increasing throttle-body diameter from 74mm to 82mm.
IPD claims gains of 20+ WHP and 15+ WTQ for this application. The 82mm Competition Plenum requires upgrading the factory 74mm throttle body to a Porsche GT3 82mm throttle body.

DasMotoring Notes
I run this exact IPD 82mm Competition Plenum and GT3 throttle-body configuration on my own 987.2 Boxster Spyder. For customers looking to maximize intake airflow, I prefer the Competition 82mm configuration over the 74mm version that retains the factory throttle body.
Please verify your exact model, engine, and throttle-body configuration before ordering.
