These air deflection plates are mounted at the rear of the engine, particularly on the underside of the cylinder plates.
These air conduction plates ensure a better reflection of the cooling air and therefore a better cooling of the 2nd and 4th cylinders. On the other side (for cylinders number 1 and 3 ), this is done by plates that are mounted like a slide under the engine (see also the Related parts tab).
In the absence of these parts, the cooling air is lost, which we must avoid with an air-cooled engine. Cooling air is essential, so it is advisable to install these parts if they are missing.
These deflectors are supplied in pairs with a black powder coating.
