DENSO Iridium Super Ignition Spark Plug FXE24HR11

Improved acceleration, efficiency and reliability

DENSO Iridium Super Ignition spark plug range is certain to improve your cars acceleration as the electrode is formed into a double thin-needle shape.

The Iridium Super Ignition double needle shape means the flame kernel develops as the engine power is drawn out to its maximum potential.

Maximum Efficiency & Performance Fitting Tip:

• Fit the DENSO spark plug with a torque wrench
• Mark the spark plug bolt on the opening next to the electrodes
• Put spark plug in at specific diameter dependent on the size of spark plug
• There will be either 2N.m, 5N.m or 10N.m, diameter dependent, to turn the spark plug for the head to align with the inlet valve

Featuring a 0.4mm iridium alloy center electrode and a 0.7mm needle-type platinum alloy ground electrode, the Iridium Super Ignition spark plugs are protected by a 360° laser welding around the iridium tip.

DENSO Iridium Super Ignition spark plugs features:

• Needle-thin electrodes allow ignition spark to grow 360° degrees for improved acceleration
• Improvement on fuel consumption due to less combustion fluctuation
• Reduced emissions as the improved ignition performance means using less CO, CO2 and HC emissions
• Offer up to three times the life service of regular spark plugs as Iridium Super Ignition are designed to last beyond 100,000 miles

Due to the smaller electrodes, the ability of the air and fuel to mix is improved which allows ignition spark to expand faster and more powerfully, improving performance and fuel economy.

DENSO's Iridium Super Ignition range features an innovative technology that has created a unique iridium rhodium alloy with the highest iridium ratio for the center electrode, and also a bespoke platinum alloy for the ground electrode, allowing for an improved lifespan.
