What is the purpose of the intercooler?
The
intercooler
cools the
compressed air
from the turbocharger before it enters the engine’s intake manifold. This process increases
air density
, leading to
improved combustion efficiency
,
more power output
, and
lower exhaust temperatures
. A properly functioning intercooler also helps reduce
engine knock
and
boosts fuel economy
.
