Detailed Description

NGK 54345 is part of the NGK Spark Plug Wire Set line, a product family focused on ignition replacement parts. NGK draws on long OE experience and high-volume automotive coverage, and this wire set reflects that approach with materials selected for durability and operational performance.

This part cross-references Anchor (e.g., 9024, 9657) for the same application.

What It Is Used For

• Restoring spark transfer when old wires have increased resistance.
• Reducing ignition noise caused by worn or degraded wire insulation.
• Replacing cracked, heat-aged, or oil-contaminated ignition wires.
• Addressing misfire symptoms linked to poor wire conductivity.

Installation Notes and Tips

Verify the vehicle’s distributor cap style before ordering; the 1981 Mercedes-Benz 280CE and 280E listings specify a screw-on distributor cap. Match each wire to the original routing and cylinder location during installation to avoid crossfire or routing stress.
