Vemo V22-70-0004 Ignition Coil

The Vemo V22-70-0004 is a high‑performance ignition coil designed to deliver reliable spark generation for a wide range of automotive engines. Its compact, robust construction and precise electrical characteristics make it an ideal replacement or upgrade component for vehicles such as the Citroën C4, C5, Expert 307, 407, 807, Peugeot 206, 307, 406, 407, 607, and many others that use a single‑coil ignition system.

Key Functional Characteristics

• Primary Voltage: 12 V DC – the coil is engineered to operate efficiently from standard automotive battery supply.
• Secondary Output: 4,000–5,500 V – sufficient to ignite modern gasoline and diesel spark plugs under a variety of operating conditions.
• Resonant Frequency: Optimized for the engine’s firing order, ensuring minimal energy loss and maximum spark intensity.
• Operating Temperature Range: -40 °C to +120 °C – guaranteeing performance in both cold climates and high‑heat engine compartments.

Design & Construction

The coil features a sealed, hermetic housing that protects internal windings from moisture, oil, and mechanical shock. The winding insulation is made of high‑grade enamel capable of withstanding the voltage spikes typical in modern ignition systems. A precision‑machined iron core provides excellent magnetic flux density, while the coil’s outer shell is fabricated from durable plastic to reduce weight without compromising structural integrity.

Installation Compatibility

The Vemo V22-70-0004 is engineered for direct fitment in a variety of vehicles that originally shipped with the same model or equivalent single‑coil ignition modules. Its dimensions match those of the original equipment, allowing technicians to install it without modification to engine bay components or wiring harnesses.

• Vehicle Families: Citroën C4, C5, Expert 307, 407, 807; Peugeot 206, 307, 406, 407, 607; and other models that use a single‑coil system.
• Connector Type: Standard spark plug terminal with integrated connector – no additional adapters required.

Performance Benefits

By delivering a clean, high‑energy spark, the Vemo V22-70-0004 enhances engine combustion efficiency. This leads to improved fuel economy, smoother idle, and reduced emissions. The coil’s low inductance design also contributes to faster ignition timing response, which is particularly beneficial in performance or high‑RPM applications.

Reliability & Durability

The component undergoes rigorous testing for electrical continuity, insulation resistance, and thermal cycling. Its robust construction ensures a long service life even under demanding operating conditions such as high ambient temperatures, frequent engine starts, or extended idling periods.

Maintenance Considerations

• Inspect the coil housing for cracks or signs of wear before installation.
• Verify that the spark plug terminals are clean and free from corrosion to maintain optimal electrical contact.
• Use a qualified diagnostic tool to confirm proper ignition timing after installation.

Technical Specifications Summary

Conclusion

The Vemo V22-70-0004 Ignition Coil stands out as a reliable, high‑performance component for modern automotive ignition systems. Its precise electrical output, durable construction, and broad vehicle compatibility make it an excellent choice for both routine replacements and performance upgrades.
