Manifolds, exhaust and emission control systems
All models utilise a light alloy inlet manifold which on carburettor models is coolant heated to improve the atomisation of the fuel/air mixture.
The exhaust manifold is of cast iron construction and incorporates a heated air box as part of the air inlet system on carburettor models.
