DENSO Iridium spark plug IUH24 for motorbike | Автомобили и мотоциклы
Описание товара
1、Projected Center Electrode
In order to improve ignitability, the center electrode protrudes more than with conventional type plugs. This improves both acceleration response time and performance.
2、0.4 mm DiameterUltra-fineIridium Center Electrode
Using a new iridium alloy with a very high melting point, the tip of the electrode can be made very fine. This enables the reduction of voltage necessary to cause the spark, and greatly improves ignitability.
3、Taper-cut Ground Electrode
The tip of the ground electrode is cut to a fine taper to reduce the adverse effects of quenching, which greatly improves fuel ignitability. Also, because of the streamlined, taper-cut shape, the fuel-air mixture spreads more evenly in the gap, resulting in steady, reliable igniting of combustion.
4、U-Groove Ground Electrode
IThe U-shaped groove on the ground electrode insures that the inside surface area is large enough to generate the flame kernel. This shape enables lower voltage needed to cause the spark and results in excellent ignitability without increasing the size of the spark gap.
5、Insulator Projection
The projection of the insulator is optimally designed based on each plug's thermal value. This corresponds to requirements unique to thermal value, such as self-cleaning ability at lower thermal values, and heat resistance at higher thermal values.
Improved Horse Power (1)
Get more power with an optimal fuel cycle
IRIDIUMPOWER has a low required voltage and a high ignitability, resulting in less misfiring and no spark, the outcome being a dramatic improvement in combustion. Engine output is thus increased. The findings of a bench test using a motorcycle engine to show the improved combustion from IRIDIUMPOWER is shown on the below. Compared to normal plugs, a 0.5ps (1.4%) improvement is seen in output at 110 km/h. Improved Acceleration Increased response and acceleration performance. IRIDIUMPOWER best demonstrates its performance improvement during acceleration. IRIDIUMPOWER has a 0.4 mm diameter iridium center electrode and a specially shaped ground electrode. These features combine to achieve higher ignitability and require lower spark voltage than ever before. This enables high-response driving with fewer misfires than under higher required voltage spark conditions, and fewer misfires when ignitability is difficult. As a result, acceleration improves in comparison with normal plugs.
Improved Horse Power (2)
The 0.4mm center electrode increases output under various driving conditions.
The power produced by the 0.4mm dia. iridium center electrode is
IRIDIUMPOWER
unmatched by other plugs. The graph below compares the resulting power when
IRIDIUMPOWER
is installed compared to other high performance plugs. Using a 0.4mm dia. fine center electrode, there is more power compared to 0.8mm and 2.5 mm dia. plugs. This is what makes the difference in acceleration and in your lap time.
Improved Fuel Mileage
Even during idling ignition is assured, with less fuel consumption.
The good ignitability from the fine electrode (0.4 mm) of
IRIDIUMPOWER
draws out much more performance from the engine. Comparing a normal plug (W20FS-U) with an
IRIDIUMPOWER
(IWF22) on a 2-cycle 50cc engine, fuel consumption improved from 41.74 km/L → 43.69 km/L, an improvement of about 5%.
Comparison of DENSO and Fake
1、Terminal
A genuine DENSO spark plug Terminal has a glossy finish. 2 、 MarkingsA fake DENSO spark plug Printed wording can be scraped off.
3、HousingA fake DENSO spark plug Poor surface finish.
4、Screws & ElectrodeA fake DENSO spark plug Poor thread quality and finish.
5、Ceramic InsulatorA fake DENSO spark plug Poorly manufactured ceramic insulator with visible air bubbles trapped within which affect heat dissipation capability.
6、Center Electrode A genuine DENSO spark plug has a copper-core center electrode with excellent heat conductivity. A fake DENSO spark plug does not, retaining heat that causes meltdown. 
DENSO Spark plug contains copper core
Quick heat dissipation
Copper is an excellent heat conductor. High temperature heat is quickly dissipated away from the center-electrode to prevent melt down. 
Fake plug is iron only
Slow heat dissipation
Absence of a copper-core center electrode results in poor heat dissipation capability. Prolonged use causes power loss due to excessive heat buildup. This results in melt down of the ground electrode, eventually leading to serious engine damage.
