RENNtech's Boost pressure gauge.

RENNtech's Boost pressure gauge offers direct visual indication of your CLA's turbo performance and available boost pressure. Our easy to ready, 67mm gauge faces features an attractive carbon composite look and mounts directly into your CLA dash without cutting or drilling. RENNtech's boost gauge features an internal microprocessor which controls the pointer (needle) movement and a digital high torque stepper motor to ensure quick, accurate pointer movements. The state of the art internals also control unwanted pointer movement or needle float found in other gauges on the market even under the most extreme motorsport conditions.

The gauge is available in both PSI and BAR readings with large, easy to read numbers in all lighting conditions and features a white illuminated background for low lighting. Settable warning LED is also available with settings for both Low and high conditions. The gauge is finished off with a stylish aluminum bezel and comes complete with all necessary line and fittings for installation. Custom colors and scales are also available.
