SUPERIOR SPARK

DENSO offers a complete range of spark plugs, delivering world-leading technology.
The range includes:

Nickel TT – A unique twin-tip electrode design to produce complete, efficient and cleaner combustion.

Iridium TT – Long-life performance plugs are 6x harder and 8x stronger than platinum. They have the highest level of iridium content (90 per cent) giving them increased oxidation resistance and allowing them to last 100,000km.

Iridium Power – High-performance plugs with the world’s smallest iridium centre electrode. Their small electrode requires less voltage, reducing misfires.

Iridium Racing – The ultimate performance spark plug for the serious racer. Precision tuned for the demands of high-rev, high-horsepower, high-torque and high-output engine applications under extreme endurance and competitive conditions.

Denso

DENSO spark plugs have a number of unique features that set them apart from the competition, like using a 1.5mm diameter nickel alloy in the Nickel TT plugs that reduces spark wear by up to 40 per cent compared to standard nickel. Another unique component is the 1.1mm diameter platinum electrodes which can withstand incredibly high temperatures. DENSO’s high-purity iridium alloy can handle the highest of temperatures and is the hardest material used for spark plugs. Iridium tips ranging between 0.4mm, 0.55mm and 0.7mm are laser-welded to the centre electrode.

DENSO uses four different terminal types:

  • Thread (no terminal nut, mainly for motorbikes and older cars)
  • Solid (solid terminal for car applications, cannot be removed)
  • Terminal (easy to unscrew, thread with nut)
  • Crimped (thread with crimped nut, better connection between nut and thread, nut can be removed)

DENSO

Vast and elite

DENSO specialises in a number of OE products, such as radiators, condensers, starters, alternators, spark plugs, sensors, air-intake systems, diesel injectors, pumps and filters. DENSO’s oxygen sensors are constructed from the highest-quality materials available; high-quality stainless steel, porous polytetrafluoroethylene (PTFE), fluorine rubber, aluminium oxide, high-grade platinum and ceramic.

DENSO

Denso oxygen sensors are resistant to silicone and lead poisoning that make it as highly sought after OE-parts by workshops. DENSO’s radiator configurations – tanks, fin pitch, core dimensions and materials – meet rigid standards and pass DENSO’s strict durability and function tests.
Likewise, DENSO’s condensers are manufactured to allow the A/C system to operate at peak efficiency with minimal maintenance, assuring years of trouble-free service.

DENSO

Denso’s starters and alternators perform to manufacturer standards, mount with a minimum of installation issues and provide years of reliable service. Highly durable components such as heavy-duty ball bearings and impact limiters prevent internal damage, resulting in products with the lowest return rates in the aftermarket.
There’s been an explosive growth in diesel-powered passenger and commercial vehicles on Australian roads. DENSO offers the world’s highest injection common-rail system of 5x injections per cycle, while retaining the ability to meet increasingly strict emission laws.
DENSO’s OE experience and know-how is reflected in its aftermarket product range providing unmatched performance, reliability and fitment with real cost savings.
