303-1 2-3 Intake Air Distribution and Filtering 303-1 2-3
DESCRIPTION AND OPERATION
lntake Air Distribution and Filtering - 1.4L Duratec-I 6V
I (Sigma)/l .6L Duratec-1 6V (Sigma)
lntake manifold
The 1.41 and 1.61 versions feature a revised intake
manifold. The overall length of the intake pipes has
been increased, but the pipes are of equal length
on all cylinders. This has resulted in increased
torque in the lower engine speed range and a
reduction in noise levels.
I 1 I Mounting for the throttle valve unit I
FIT-MAP sensor I
The mounting for the electronic throttle valve is
located inside the intake manifold between the
intake pipes of cylinders 1 and 2. The T-MAP
sensor, which is used on both the 1.41 and 1.61
versions, is situated next to the throttle valve unit.
