Powersprint Weld-In Lambda Sensor Boss with Plug

The boss is welded onto the pipe or onto the catalyst and leaves an M18x1.5 thread for the lambda sensor. When the port is not in use, the plug supplied with it closes the hole so no gas escapes past it.

Specifications

Where it goes

• When fitting a lambda sensor on a line built to order.
• On catalysts and cartridges supplied without a sensor port.
