For each exhaust tract, four corre

sponding oxygen sensors regulate
the composition of the exhaust
gas and monitor the conversion
of pollutants in the cataly tic con -
verters.
A sports exhaust system – for
a
more resonant sound – is
available as an option for

each of the Cayman models.
Ignition system.
The ignition system is designed
for static high -voltage distribution.
Individual ignition coils on each
of the spark plugs ensure perfect
ignition every time. The individual
ignition coils are controlled
directly by the engine electronics.
Servicing.
It is a good idea to have your
vehicle serviced regularly, but it
makes just as much sense to keep
the time bet ween maintenance
services as long as possible. Why?
Because a Porsche belongs on
the road, and not in the workshop.
The alternator, power-steering
pump and the air- conditioning
compressor are all driven by a
Exhaust system.
The exhaust system – with t win
tailpipes on the Cayman S – is
made of stainless steel. Until it
converges in the connecting tube,
the exhaust gas is channelled
through t wo separate tracts and,
thanks to separate exhaust gas
cleaning systems, the exhaust
gas can flow more freely – for
increased power and torque.
The stereo Lambda control
single self-adjusting belt. Hydraulic
valve clearance compensation
makes valve clearance adjustment
unnecessary. The drive chains
on the camshaf ts do not normally
require servicing. With the sole
exception of the spark plugs,
the ignition system is also
maintenance-free.
Put simply, we don’t expect to
see your Porsche too often.
