Denso’s latest generation of high performance iridium spark plugs with the worlds first ultra-fine 0.4mm diameter iridium centre electrode. Patented Iridium-Rhodium alloy is 6x harder and 8x stronger than platinim making it extremely tough and wear-resistant. By using a 0.4mm diameter iridium alloy center electrode and a special ground electrode, IRIDIUM POWER realises spark performance unseen until now. It steadily gives a high level of response under a variety of driving conditions. The result? Increased acceleration and torque compared to regular plugs.

Improved Output - Iridium Power’s 0.4mm dia. Iridium center electode and specially shaped ground electrode has a low required voltage, gives high ignitability, resulting in less misfiring and always a spark, the outcome being a dramatic improvement in combustion. This significantly improved combustion enables the engine output to increase. Acceleration is superior to normal plugs.

Improved Power - The power produced by the 0.4 mm electrode is unmatched by any other plugs. Using a 0.4mm dia. fine centre electrode there is more power than with 0.8mm and 2.5mm plugs.

Improved Fuel Consumption

• The excellent ignitability of Iridium Power’s 0.4mm fine electrode draws out much more performance from the engine.
• Tests show fuel consumption improves by around 5%.
• Decreased CO2 emissions.
