Perkins 4.154 Thermostart

A good quality aftermarket Perkins 4.154 12v heater plug (thermostat). It can be supplied with either the 'spade' or alternative 'screw' type electrical connection. This part fits into the inlet manifold and is not suitable for the later 4.154 200 series.

A burnt-out coil on your glowplug is often one of the main causes of poor cold weather starting. They are easily replaced and it's worth keeping a spare if you are operating in the marine environment!
