Setup, Compatibility & Care
Compatibility:
Before installation, verify that the NGK 5598 Spark Plug (PTR6D-13) is listed as compatible with your specific vehicle's make, model, and year. Consult your vehicle's owner's manual or a trusted automotive parts database.
Installation:
- Ensure the engine is cool.
- Remove the old spark plug using the appropriate size wrench (16mm spanner size for this plug).
- Check the gap of the new spark plug using a feeler gauge and adjust if necessary according to your vehicle manufacturer's specifications.
- Carefully thread the new spark plug into the cylinder head by hand to avoid cross-threading.
- Tighten the spark plug using a torque wrench to the manufacturer's recommended torque specification. Over-tightening can damage the cylinder head or the plug.
- Reconnect the spark plug wire or ignition coil.
Care:
Spark plugs are typically a maintenance item and are not designed for user servicing beyond checking the gap during installation. If a spark plug appears fouled or damaged, it should be replaced.
