GFB Gauge Port Mark 5/6 GTI
SKU: G004 5800
Description
Part #: 5800
Most modern engines have eliminated vacuum ports from the intake manifold, making it difficult to install boost gauges, boost controllers, aftermarket blow-off valves and other devices that require a signal from the intake manifold.
GFB's Gauge Port range allows a quick and tidy solution by tapping into existing features on the intake manifold to provide an extra reference port.
