Key specifications
Material: Ceramics
Type: Resistor spark plug
Model: F5RTC
Warranty: 24 months
How to use
Before installation, ensure the engine is completely cool to prevent burns and damage to the cylinder head threads. Remove the spark plug wire, clean the area around the old plug to prevent debris from entering the combustion chamber, and unscrew the old unit using a spark plug wrench. Carefully insert the new Grimsholm F5RTC spark plug by hand to avoid cross-threading, then tighten it to the torque specification recommended by your lawnmower manufacturer. Finally, reattach the spark plug wire securely.
What to consider before purchase
Verify that your lawnmower engine manual specifies the F5RTC type
Check the thread size and reach of your current spark plug
Ensure the engine is compatible with resistor-type plugs
Usage recommendations
Regularly inspect the spark plug for carbon buildup or electrode wear to ensure peak engine performance. Replace the spark plug according to the maintenance schedule provided in your lawnmower's user manual to prevent ignition failure.
