Rothsport-designed Intake Systems
When it comes to air-cooled Porsche 911 engines, sometimes we like to create our own recipe. Getting air into the engine is one of the most critical areas we have taken great quantities of time to develop.
Slide Valve EFI
The slide value configuration represents the ultimate in performance and racing engines by providing exceptional intake performance and throttle response. The throttle slides are CNC machined out of aircraft alloys and feature a modular design which allows either trumpet or plenum intake systems. The slide actuating systems has an innovative design to prevent inclusion into the intake stream. The system can be sized for all 6-cylinder air and water cooled engines.
This system incorporates a simple throttle linkage assembly which is designed to utilize the stock throttle rod.
