Opel Frontera UBS. Service manual — part 1414
6J – 2 INDUCTION
There is a large intake silencer provided at the entrance
of the air cleaner. Air cleaner element is a viscous type
which features high filtration efficiency.
A resonator is used also in the air duct between the air
cleaner and turbocharger to reduce air intake noise.
The air taken in flows through the turbocharger to the
intercooler where the air is cooled and then taken in the
cylinder through the intake manifold.
