Description An aluminium M12 x 1.5mm threaded boss for coolant or air temperature sensors, etc. 20mm wide x 14mm tall. Stainless steel ones are available in a separate listing. Note: These bosses will need cutting down to approx. 10mm height for use with our universal M12x1.5mm air temperature sensor. They are fine as they are for the coolant / oil temperature probes.
