The hot spot is a thermally conductive insert fitted to the inlet manifold on the Land Rover Series 2 and 2A 2-litre diesel engine, designed to transfer heat from the exhaust manifold to the incoming air-fuel mixture to aid cold starting and improve fuel vaporisation at low temperatures. A worn or deteriorated hot spot reduces heating efficiency, leading to hard cold starts, excessive white smoke, and poor running until the engine reaches operating temperature. Replacing a failed hot spot restores correct thermal transfer and ensures reliable engine operation in cold conditions. Key Features Manufactured to fit the inlet manifold hot spot location specific to the Series 2 and 2A 2-litre diesel engine Direct replacement component - no modification required for fitment Supplied as a Britpart part, conforming to original Land Rover specification references When replacing, inspect the surrounding manifold gaskets and mating faces for warping or gas leakage Vehicle Fitment This hot spot is compatible with Land Rover Series 2 and Series 2A models fitted with the 2-litre diesel engine.
