Engine Covers
There are 2 engine covers, which are identified here as the
key switch cover and the air intake elbow cover.
The key switch cover serves as the housing for the ignition
key switch and/or throttle lever, if equipped, and is always
fastened to the blower housing. The air intake elbow cover
has a contoured opening to accommodate the air intake
elbow, and is variously fastened to other bracketry or
components, such as the fuel pump module bracket, air
cleaner bracket, air intake elbow, etc.
The air intake elbow cover is absent on those models
equipped with the low profile air cleaner.
Cover appearance may differ based on model and/or options.
