CIS Warm Up Regulator Digital

Product Description:

Digital WUR for Naturally Aspirated Engines
If we show out of stock, contact us for lead time.

The warm up regulator is crucial to the correct operation of the CIS Fuel system. Bosch has discontinued most if not all of the original warm up regulators used in the CIS fuel injection system. If you don’t have a rebuildable original WUR core for your 911, this digital model is a great alternative.

This digital WUR is for the Porsche 911 CIS models, 1973.5 to 1983. It replaces the original mechanical style regulator and is a direct fit into the same location. The digital WUR uses an electronic frequency valve and a temperature sensor to accurately deliver a precise "Control Pressure" under all operating conditions. Comes with a 15 page owner’s manual including installation instructions.

This unit comes with a base program already installed. If you want to be able to program the settings, we offer a communication interface.

On 1975-83 vehicles that are still stock, no modifications should be necessary to install this unit. The 1973.5-1974 models may require some fitting changes depending on the model of WUR currently installed. We offer a conversion kit that allows early CIS cars to accept later WURs or the digital WUR.

We also carry a digital WUR version for Porsche 930 models with CIS.

Manufacturer Information:

Aftermarket
Our founders have worked on Porsche cars for decades. They've tried most of our aftermarket products first hand on real cars. Some parts are no longer made by an O.E.M company, or the price difference between genuine and aftermarket has become so large that it makes sense to take the savings. If you have any questions about an aftermarket product, please contact us.
