Range Rover Sport L494 3.0 supercharged V6 petrol: spark plugs

Ignition · Range Rover Sport L494 (2013–22) · 2013–2022

How often: every 100,000 mi or 7 yrs, whichever comes first. Worn plugs cause misfires that can damage the catalytic converters.

Check the plug interval on your Maintenance Check Sheet; Land Rover's varies by engine.

Work safely: support the vehicle on axle stands, never a jack alone; let it cool first. Check figures against your workshop manual. You do this work at your own risk.

Parts

Spark plugs (long-life plugs to suit engine (one per cylinder)) LR050998

Tools

Trim tools for coil covers

Step by step

Remove the engine covers and the coils one at a time.
Blow dirt out of the plug wells before removing each plug.
Fit the new plugs to the specified torque; don't use anti-seize unless your manual says so.
Refit the coils firmly and clear any misfire codes.
