Detailed Product Description

The Champion Platinum Power 3405 spark plug features a platinum center electrode tip that improves wear resistance and extends service life compared to conventional spark plugs. The ground electrode is constructed from a nickel copper alloy, providing a stable and consistent spark. This plug includes a non-removable nut electrical terminal, ensuring a secure and reliable connection within the ignition system. With a flat seat design and a reach of 0.75 inches, it fits precisely in compatible engines. The pre-gap size of 0.035 inches (0.89 mm) is factory set to optimize ignition timing and combustion efficiency. Additionally, the resistor built into the plug helps minimize radio frequency interference, supporting smooth vehicle electronics operation.

Compatible Vehicles and Applications

This spark plug is compatible with a broad range of makes and models, including but not limited to Audi 318i, BMW 325i, Ford Mustang, Honda Civic, Toyota 4Runner, and Volkswagen Jetta. It is suitable for use in secondary ignition systems where a platinum spark plug with these specifications is required. The part number 3405 corresponds to the Champion Platinum Power line, ensuring fitment for vehicles requiring a 14mm thread diameter and a heat range of 14.

• Improves ignition reliability in older and newer engines
• Helps resolve misfires and rough idling issues
• Reduces fouling and electrode wear over time
• Supports consistent engine starting and acceleration
• Minimizes electrical interference affecting vehicle electronics

Installation Notes and Tips

Before installation, verify the spark plug gap matches the vehicle manufacturer’s specifications; the Champion 3405 comes pre-gapped at 0.035 inches (0.89 mm). Use a torque wrench to tighten the spark plug to the recommended torque to avoid damage to the threads or insulator. The hex size of 13/16 inch (0.813 inch) allows for standard spark plug sockets. Inspect the ignition coil boots and wiring for wear during replacement to ensure optimal performance.
