AThe engine specifications for output and torque listed in this table are based on the use of premium fuel.
Charge air cooler (Intercooler)
The engine employs a turbo-compressor to
force air into the engine intake manifold and a
charge air cooler to cool the compressed inletair. The resulting increase in air flow raises
pressure in the intake manifold and increases
engine power over that developed by the nor-
mally-aspirated engine. The charge air cooler(which resembles a radiator) is located
between the turbo-compressor and intake
manifold.

Three-way catalytic converter

281 Three-way catalytic converter –
general information
•Keep your engine properly tuned. Certain
engine malfunctions, particularly involving
the electrical, fuel or distributor ignition
systems, may cause unusually high three-
way catalytic converter temperatures. Do
not continue to operate your vehicle if you
detect engine misfire, noticeable loss of
power or other unusual operating condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will help
avoid malfunctions that could damage the
three-way catalytic converter.
•Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot exhaust
system and cause such materials to ignite
under certain wind and weather condi-
tions.
•Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way cata-
lytic converter or exhaust system over-
heating.
•Remember that tampering or unauthorized
modifications to the engine, the Electronic
Control Module, or the vehicle may be ille-
gal and can cause three-way catalytic con-
verter or exhaust system overheating. This
includes: altering fuel injection settings or
components, altering emission systemcomponents or location, or removing com-
ponents, and/the repeated use of leaded
fuel.
NOTE
Unleaded fuel is required for vehicles with
three-way catalytic converters.
