An excellent reproduction of the 1974 RSR slide valve induction system. Fits all classic 911s.
This German-made system has several improvements over the original factory parts, including higher quality bearings and tolerances.
The EB Motorsport Porsche slide throttle intake system is track-proven and requires little maintenance, nowhere near as prone to the sticking throttle issues of the original parts.
The standard system has 46mm bores, but can be supplied with other sizes on request, to suit engines including 2.3, 2.8, 3.0 and above.
Modelled on original parts, the EB High Butterfly Intake System retains many historic features, which other reproductions omit on the basis of production cost and engineering complication.
EB Motorsport high butterfly throttles include individual balancing screws, brass linkage bushes with grease nipples at the transmission end and original-style webbing between the stacks for added strength.
Initially available with 43mm Intake Ports and 50mm butterflies to suit Porsche 911 3.0 RS and RSR engines, EB high butterflies come with all the linkage parts required for installation on a MFI Porsche 911 engine.
