WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2021 MINI Cooper, 2020 MINI Cooper, 2019 MINI Cooper, 2018 MINI Cooper, and 2017 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
Ignition coils must not be contaminated by fuel.
The resistance of the silicone material is reduced significantly by contact with fuel, which may cause the ignition coil to fail!
The silicone tube of the spark plug socket is coated with talcum powder to reduce the pulling forces. The silicone tube must NOT be oiled or greased. This would greatly reduce the durability of the silicone material, which can lead to a failure of the ignition coil.
