Installation Guide

1. Preparation: Warm up the engine to operating temperature, then turn off the ignition.
2. Remove Old Plug: Use a spark plug socket and ratchet to unscrew the existing plug. Inspect for damage or excessive wear.
3. Check Gap: Verify that the electrode gap matches the manufacturer’s specification (typically 0.7–1.2 mm). Adjust with a gap gauge if necessary.
4. Install New Plug: Hand‑tighten the Z273, then use a torque wrench to apply the correct torque (usually 100–120 Nm, check your vehicle’s service manual).
5. Final Check: Inspect for proper seating and ensure no cross‑threading occurred.

Performance Benefits

• Enhanced Combustion Efficiency: The precise spark timing improves fuel burn, leading to better mileage.
• Reduced Engine Knock: Consistent spark reduces pre‑ignition and knocking, protecting engine components.
• Lower Emissions: Efficient combustion results in fewer unburnt hydrocarbons released into the atmosphere.
• Longer Service Life: High‑quality materials resist wear, allowing for extended intervals between replacements.

Maintenance Tips

To keep your BERU Z273 Spark Plug operating at peak performance, follow these simple practices:

• Regular Inspection: Check the plug every 10,000–15,000 km or as recommended by your vehicle’s maintenance schedule.
• Avoid Over‑Torqueing: Excessive torque can damage threads and reduce spark quality.
• Keep the Socket Clean: Remove debris from the socket to prevent cross‑threading during installation.
• Use Correct Gap Gauge: A properly gapped plug ensures optimal ignition timing.
