DESCRIPTION OF STRUCTURE AND 
OPERATION

.

PremAir

â* direct ozone reduction (DOR) radiator

A catalyst which reduces ozone (O

3

) in the ambient 

air has been applied to the radiator core. The radia-
tor offers a suitable surface area and operating tem-
perature range to facilitate catalytic reduction of 
ozone across the PremAir

â* radiator.  When ozone 

(O

3

) contained in the ambient air passes across the 

catalyst, the ozone (O

3

) is reduced to Oxygen (O

2

), 

and reduces pollution in the air. Vehicles with the 
DOR catalyst applied to the radiator have the follow-
ing WARNING label near the headlight (RH) in the 
engine compartment.

WARNING: ADDITIONAL EMISSION CONTROL 
INFORMATION.THIS VEHICLE IS EQUIPPED 
WITH A PremAir

â* DIRECT OZONE REDUCTION 

(DOR) RADIATOR.REPLACEMENT OF THIS EMIS-
SION CONTROL COMPONENT OF THIS EMIS-
SION CONTROLCOMPONENT WITH A NON-DOR 
RADIATOR IS A VIOLATION OF AIR POLLUTION

•

A front air intake system that actively sucks cool-
ing air from the front through the top of the radia-
tor improves engine performance and reduces air 
intake noise.

•

Environmentally friendly unleaded rubber materi-
als are used for the air intake hose.

•

A large air cleaner resonator has been installed 
on the locker cover to increase engine perfor-
mance and reduce air intake noise. <2.4L
