Mountfield Spark Plugs
Check the engine details before ordering, as the correct Mountfield spark plug is best matched using the machine model number or the plug part number already fitted.

Frequently Asked Questions
How do I find the right spark plug?
Choose the plug by the identification numbers on the engine fitted to your Mountfield machine. That matches the spark plug to the engine itself rather than relying on the machine alone.
Do V-twin engines need two spark plugs?
Yes, a V-twin engine takes a pair of spark plugs. If your machine has a V-twin fitted, order two so both cylinders are covered.
Why fit a new spark plug at service time?
A fresh spark plug with the correct gap at each service helps support easy starting and clean running. Replacing it as part of routine servicing keeps the engine performing as intended.
