Care information

Iridium spark plugs typically have a life span of around 100.000 km.
We still advise to change the plugs every 60.000km, especially if your car has received a few performance upgrades.
Check the spark plugs with every oil change.

If they show one (or more) of the following damages, it's time to change them:

- Corroded spark plug housing
- Oil in the spark plug well
- Carbonised electrodes
- Build-up on the spark plug
- Broken insulator base
- Discolouration on the insulator

Workshops systematically check the spark plugs during maintenance
