Spark Plug Wire Replacement

Clean and inspect the spark plug wires for burns, cracks or other damage. Inspect the spark plug wire boots for proper fit at the DIS module and at the spark plugs. Replace the spark plug wires every 96 000 km (60,000 mi). Replace the spark plug wires sooner if damage is evident.
