• Inline‑4 and inline‑3 engines with displacement ranging from 1.0L to 2.5L.
• Engines equipped with direct injection or port injection systems.
• Vehicles requiring medium heat range spark plugs for balanced performance and longevity.

Vehicle Examples (Illustrative)

While the plug is not tied to a single make or model, it has been successfully used in:

• Compact cars with 1.2L to 1.4L engines.
• Mid‑size sedans featuring 2.0L to 2.5L engines.

Installation Guide

Installing the BOSAL 099-589 Spark Plug is a straightforward process that can be completed with basic hand tools. Follow these steps for optimal results:

1. Prepare the Engine: Ensure the engine is cool and disconnect the battery to prevent accidental electrical discharge.
2. Remove the Old Plug: Use a spark plug socket and ratchet to unscrew the existing plug. Inspect for damage or excessive wear.
3. Check the Gap: Measure the spark gap with a feeler gauge. Adjust if necessary to match OEM specifications.
4. Install the New Plug: Hand‑tighten the plug into the cylinder head, then use a torque wrench to achieve the manufacturer’s recommended torque (typically 100–120 Nm for most engines).
5. Reconnect the Battery: Reattach the battery terminals and start the engine to verify smooth operation.

Maintenance & Care Tips

To maximize the lifespan and performance of your BOSAL 099-589 Spark Plug, adhere to these maintenance practices:

• Inspect plugs at every oil change or every 10,000 miles (whichever comes first).
• Avoid using excessive force when removing plugs; use a spark plug socket with an extension to prevent damage.
• Keep the engine bay clean and free of oil or coolant leaks that could contaminate the plug.
• Store unused plugs in a dry, dust‑free environment to preserve the ceramic insulator.
