Product Description

Performance Design Intake
Performance Design Intake

Lighten the Load, not the Look!

The plenum is constructed from high strength carbon fiber with high temp epoxy for improved strength to weight ratio and reduced heat soak. A polymer lower intake further resists heat soak and houses all ports/sensors underneath the valley for a clean look. This combination of materials offers a 10 pound weight savings over aluminum tunnel ram manifolds.

About Performance Designs

Performance Design was born out of a passion for product design and development to serve companies who don’t have the in-house capacity or expertise. Along the way we began to design, develop and manufacture our own line of performance products for racers and enthusiasts. We continue to serve both markets today.
