DENSO IRIDIUM LONG LIFE SPARK PLUGS
The latest DENSO development is a revolutionary
new generation of spark plugs. These spark plugs
feature a centre electrode made of a special
iridium alloy. After 15 years of experience with double
platinum spark plugs, DENSO takes a step into the
future with this innovative new material.
DENSO iridium SK spark plugs have been develop for the
latest generation of engines, and can easily exceed service
intervals of 100.000 km. The DENSO iridium alloy has a
higher resistance to wear than platinum, which allows
the centre electrode diameter to be reduced to 0.7mm.
DENSO iridium spark plugs are fitted as standard to the
new Lexus, Avensis and Hiace. For the new leanburn
Avensis DENSO supplies 100% of the spark plugs fitted
as original equipment.
DENSO iridium spark plugs offer:
(1) - Service life over 100.000 km
(2) - Very low voltage required throughout service life
(3) - Ability to ignite lean air/fuel mixtures
(4) - High performance combined with long life
(5) - Improved emission control

World’s Smallest Diameter



Also,

Using a platinum-tipped ground electrode to realize high-performance operation and long life.
A Platinium tip was used, which has a long history of use in platinum plugs. By signigicantly controlling electrode wear, we've achieved a level of durability equal to that of platiunum plugs.
High Strength Insulator

Using a high-strength insulator specially designed for taxis.
By using a high-strength ceramic insulator for LPG engines, a 20% increase in strength was achieved over conventional insulators.
Improved Mileage

Less fuel consumption with a 0.4mm diameter center electrode.
Even during idling, when it is easy for ignition to degrade, IRIDIUM PLUS reduces mis-sparking and stabilizes idling speed. This results in a quieter engine and improved fuel consumption.

Improved Acceleration

Through steady ignitability, acceleration performance is greatly improved.
IRIDIUM PLUS, through its 0.4mm diameter iridium center electrode, has realized high ignition performance and low spark voltage at levels heretofore unseen. Because of this, there is less non-firing under high spark voltage conditions and fewer misfires under conditions where ignition is difficult, permitting operation with a high level of response under a variety of conditions. As a result, acceleration has been improved.
Acceleration comparison

*Vehicle: 250cc
(2 cycle water cooled, V2 cylinders)
Conditions: Locked in 6th gear, starting at 50km/h on
an automatic test device and accelerating at full throttle.
*The data shown is from internal
studies. Also, the "Regular Plug"
and "Platinum Plug" referred to
here are DENSO products.
Excellent Durability

Realizing astounding life and durability with platinum ground electrodes.
By welding a platinum tip to the ground electrode, wear has been controlled to a significant extent in the IRIDIUM PLUS. In addition to acceleration performance, the life and durability of this plug has been increased to that of a platinum plug.

Durability Comparison

*From taxi monitoring test results. Exhaust volume was for the most part 2000cc.
*Durability will differ depending on the driving conditions.
*The service lifetime of IRIDIUM PLUS will depend on operating conditions and the vehicle it is installed on. (Service lifetime may become shorter depending on the vehicle’s ignition system.)
*Recommended time before replacement is not something that must be followed to guarantee quality.
*The data shown is from internal studies. Also, the "Regular Plug" and "Platinum Plug" referred to here are DENSO products.
