Spark Plug Rubber Rod

The function of the spark plug rubber rod：

• High-voltage wire dust cover: Protect the connection part between the spark plug and the ignition or high-voltage wire, prevent dust and oil from entering, and avoid electric leakage.
• Sealing and insulation: Resistant to high temperatures, rubber such silicone can withstand the high temperature of the engine and insulate to prevent high voltage short circuit.
• Shock absorption and water resistance: Buffer engine vibration to avoid connections; some designs have waterproof functions.
• Common issues and maintenance: - Aging cracks: High temperatures and chemical corrosion can cause rubber to harden and crack, requiring timely replacement to prevent issues like electric leakage and poor ignition.

Check suggestions：

• Regularly inspect the spark plug rubber boot for cracks or deformation, and replace it promptly if any are found.
• Avoid violent and tugging during disassembly to prevent the rubber boot from tearing, and avoid collisions during later spark plug installation.

The function of the spark plug rubber rod:

Installation guide: Some spark plug rubber rods are designed with guide grooves to facilitate the precise insertion of the plug into the cylinder head during installation, avoiding oblique installation.

Disassembly protection: When repairing and disassembling, it can reduce the friction between the spark plug and the hole, avoiding thread scratches and bumps.
