•  Supports smooth idle and clean acceleration
•  Helps maintain engine power and fuel efficiency

Why Replace This Part?
Spark plugs are normal ignition service items and wear over time. The electrode gap can increase, the firing tip can become worn, and the plug can become fouled by fuel, oil or carbon deposits. Worn spark plugs may cause poor starting, rough idle, hesitation, misfires, reduced fuel economy and loss of performance. On hybrid Porsche models, reliable ignition performance is especially important because the petrol engine may start and stop more frequently during hybrid operation. Replacing the spark plugs with Genuine Porsche OE spark plugs helps restore correct ignition performance and keeps the V6 hybrid powertrain running as intended.

When to Replace This Part
•   During scheduled spark plug service
•   If the engine has a misfire or rough idle
•   If starting or hybrid engine restart becomes less smooth
•   If acceleration feels hesitant or uneven
•   If fuel economy has reduced
•   If spark plugs are fouled, worn or damaged
•   During ignition coil replacement or ignition system service
•   When recommissioning a vehicle with unknown service history.

Where It Fits on the Car
This spark plug fits in the engine cylinder head, with one spark plug fitted per cylinder. It works with the ignition coil to generate the spark required for combustion in the V6 petrol engine. Correct installation torque and Porsche workshop procedures should always be followed. Ignition coils, plug wells and coil seals should be inspected during replacement.
