Design Features That Enhance Performance

• Advanced Electrode Geometry: The earthed electrode design reduces arcing and promotes uniform flame propagation, leading to smoother idle and better throttle response.
• High‑Temperature Ceramic Insulator: Provides superior heat dissipation, maintaining optimal spark energy even under high engine loads.
• Robust Threading (M14x1.25): Ensures a secure fit in the cylinder head, minimizing the risk of misalignment or loosening during operation.
• Optimized Heat Range: The 14F‑6 heat rating balances between preventing fouling and avoiding excessive heat soak, making it suitable for both everyday driving and spirited performance.

Installation Guidelines

1. Remove the old spark plug using a properly sized socket or wrench.
2. Inspect the cylinder head for any damage or debris; clean if necessary.
3. Apply anti‑seize compound to the threads of the new Beru Z349 (optional but recommended).
4. Screw in the spark plug by hand until it is snug, then torque to the manufacturer’s specification using a calibrated torque wrench.
5. Reconnect the ignition coil or distributor cap and ensure all connections are secure.
