AIR DUCT AND AIR CLEANERM2150004000656
A front air intake system that actively sucks cooling
air from the front through the top of the radiator has
been adopted in order to improve engine perfor
-
mance and reduce air intake noise.

The intake manifold is made of plastic for weight
reduction, and the surface roughness of the inner
walls of the ports has been improved to reduce
intake resistance.

A clamshell type exhaust manifold is used.

A SUS pipe type exhaust manifold is used.
EXHAUST PIPE AND MUFFLERM2150003000783
The exhaust system is composed of the front
exhaust pipe, center exhaust pipe, and main muffler,
and it has the following characteristics.•Fewer, more environmentally-friendly rubber
hangers to reduce vibration from exhaust system.
•Straighter exhaust pipe to reduce noise.

GENERAL INFORMATIONM2140000100780
The cooling system is a water-cooled pressurized,
forced circulation type which offers the following fea
-
tures.
•To stabilize engine coolant temperature, the ther-
mostat is located at the coolant inlet port from the
radiator.
•To improve engine cooling performance and save
weight, a plastic tank and aluminum radiator fins
are used.
