You're bidding on 4pcs of spark plug. Normally, each car requires 4, 6 or 8 plugs, so it depends on your model of car. If you're unsure, please check your user manual or with your mechanic. These are long life, high performance Dual tip Iridium+platinum spark plugs made in Germany. Please read below for more information before bidding. These plugs are model 6ZX-8 (same as 6ZX-11), mainly for TOYOTA/HONDA (and many other makes out there! (please refer to this guide for the exact models covered -http://www.volker-iridium.com/TOYOTA.pdf ), but other makes as well (please confirm with me before buying!!). 

This is the equivalent of DENSO IK20 and NGK BKR7EIX11 in terms of fitting.

Spark plug primary function Spark plug is part of ignition component that force high electric energy, discharge the load of electric energy at the spark plug gap and ignite mixture of air and fuel inside combustion room. Spark plugs also working under high cylinder pressures and vibration from the engines.

Another important function is to remove the heat out from combustion room. More than 50% heat dissipated through spark plug metal shell especially at spark plug thread section.

Introducing Volker Iridium spark plug, German patented Twin-tip technology Iridium spark plug uses Ø 0.5 mm Super Iridium alloy center electrode with Ø 1.0 Platinum alloy tipped ground electrode. Volker Iridium adopted Volker Nano-Crystalline technology for processing 99.5% pure Iridium + 0.05% Osmium and Rhodium composites metal. The metals are sintered in 2400 °C Hydrogen environment produce SUPER IRIDIUM alloy which outperformed normal Iridium Volker spark plug electrodes designed in such way to guide the spark to be more concentrated (focused) and create higher intensity plasma arc spark.

(*) Plasma arc spark: Higher intensity electric energy discharge across spark gap.

Volker Iridium uses Ø 0.5 mm Super Iridium alloy center electrode and Ø 1.0 mm Platinum alloy tipped ground electrode as standard.

With Volker Iridium – plasma arc spark also provides:

• Up to 37% more horse power and torque output.

• More stable ignition and stable solid acceleration.

• Prevent mis-fire.

• Improves cold and morning initial start.

 • Cleaner combustion room (sweep away all unburned fuel residual) improved engine life time.

• Reduce exhaust emission as combustion efficiency improved.

• Reduce fuel consumption.

• Save costly catalytic converter.

• Maintain longevity secondary ignition parts with 6,000 volt lower energy consumption.

(*) Secondary ignition parts: Ignition coil, spark plug cable and spark plug cap. With lower 6,000 volt energy consumption means that secondary ignition parts work with less strain, colder working temperature and maintenance free.

Why spark plug need replacement? Every time a spark plug spark, a tiny amount of metal is vaporize and lost from both electrodes. Especially the center electrode suffers the most wear from heat erosion. As the electrode wear, the spark plug gap becomewider and wider and need more voltage to spark across the gap and the ignition function start to mis-fire and may cause engine damages.
