04-006 Ignition Rotor - VW Beetle, Karmann Ghia, Transporter

Ignition Rotor – 04006

The 04006 is a precision-engineered ignition rotor designed for classic air-cooled Volkswagen engines. This component is responsible for distributing high-voltage electricity from the ignition coil to the correct spark plug terminal within the distributor cap. As the engine runs, the rotor spins at half the crankshaft speed, ensuring each cylinder fires at the exact moment required for efficient combustion.

Constructed with a premium brass tip, the 04006 provides superior electrical conductivity and significantly higher resistance to corrosion compared to cheaper aluminum alternatives. It also features a built-in resistor to suppress radio frequency interference (RFI), protecting your vehicle's electronics and preventing "noise" in the radio signal.

Product Highlights & Features

• Brass Contact Tip: Ensures a strong, consistent spark and prevents the premature pitting and oxidation common in lower-quality rotors.

• RFI Suppression: Includes a built-in 5k Ohm resistor to reduce electrical interference without compromising the energy delivered to the spark plugs.

• Durable Housing: Molded from high-dielectric materials to prevent voltage "leakage" or tracking to the distributor shaft.

• OEM Standard: Manufactured to the original specifications used by Volkswagen during the production of these classic models.

Technical Specifications

• Part Number: 04006

• Interchange: 04-006, 113-905-225, 111-905-225F

• Resistor Value: 5k Ohm

Installation & Maintenance Tips

• Proper Seating: Ensure the rotor is pushed completely down onto the distributor shaft. The small notch inside the rotor must align with the groove on the shaft; failure to do this will result in the rotor hitting the distributor cap and breaking.

• Distributor Cap Inspection: When replacing the rotor, always check the underside of the distributor cap for cracks, carbon tracks, or worn-down terminals.

• Maintenance Schedule: Ignition rotors should be inspected every 10,000 miles for signs of wear or carbon buildup at the tip.

• Contact Cleaning: If you notice light oxidation on the brass tip, you can gently clean it with fine-grit sandpaper to restore conductivity, though replacement is always preferred for consistent performance.
