DENSO Iridium Power Spark Plug IKH24
Improved acceleration, efficiency and reliability
DENSO Iridium Power spark plug range is certain to improve your cars acceleration as the electrode is formed into a double thin-needle shape.
The Iridium Power 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
Diameter Torque 8mm 8-10N.m 10mm 10-15N.m 12mm 15-20N.m 14mm 20-30N.m
Featuring a 0.4mm iridium alloy center electrode and a 0.7mm needle-type platinum alloy ground electrode, the Iridium Power spark plugs are protected by a 360° laser welding around the iridium tip.
DENSO Iridium Power 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 Power 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 Power 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.

DENSO Performance Spark Plugs
DENSO Iridium TT spark plugs are the most technologically advanced spark plug in the market designed to improve your cars performance.
Developing their spark plug range in-house, DENSO warehouses conform to QS 9000 and ISO 9000 matching high-end performance with exceptional manufacturing.
The Iridium TT range feature a twin-tip technology developed by DENSO, that features the smallest mass-produced iridium centre electrode at 0.4mm, whilst the 0.7mm platinum ground electrode is the smallest possible without reducing grounding strength or increasing electrode wear.
DENSO Iridium TT electrodes allow for less obstruction for the ignition spark which in turn produces a more complete combustion, helping to increase power and improved fuel economy, whilst the 360° degrees laser welding around the iridium tip ensures full protection and extended durability.
The DENSO Iridium TT range offers an excellent value for money spark plug certain to last over 100,000 miles, whilst improving horsepower and fuel economy and reducing harmful CO, CO2 and HC emissions due to enhanced fuel efficiency.
