Spark plugs replacement cost
for a Toyota Hilux

Replacing the spark plugs on a Toyota Hilux involves removing the ignition coils and old plugs from the engine, then installing new ones with the correct gap and torque. The cost is driven by the number of cylinders (4 or 6) which dictates the number of plugs, and whether the engine bay is easily accessible or requires more time for disassembly.

Tips before you pay

Use OEM-spec plugs (e.g., Denso) to ensure proper performance and fuel economy.
Check and replace ignition coil boots if they are cracked or brittle during the job.
Apply a small amount of anti-seize compound to the plug threads to prevent seizing in the aluminum cylinder head.
