Overview
This intake manifold is designed for the Porsche 911 991.2 GT3 and GT3 RS 4.0L naturally aspirated flat-six. An improved manifold design supports airflow to all six cylinders more consistently, contributing to a stronger mid-range charge delivery across the rev range.
Why Upgrade?
- Improved exhaust flow distribution across all six cylinders
- Suits the naturally aspirated 991.2 GT3 and GT3 RS 4.0L
- More consistent cylinder filling across the rev range
- Direct replacement for the factory exhaust manifold
Built for the Drive, Not Just the Dyno
The 991.2 GT3's 4.0L flat-six is one of the last great naturally aspirated engines, which means every cylinder filling evenly matters more here than on a turbocharged platform — there's no boost to paper over an uneven manifold. This is the kind of fix that shows up as a stronger, more linear pull through the rev range rather than a single headline number.
