Iridium, only at DENSO! Using 0.4mm dia. iridium center electrode, IRIDIUM POWER displays superb ignitability and low required voltage, drawing out better performance from your car - increased acceleration, accelerator response, operational stability, and lower fuel consumption. On the circuit, the sharp acceleration and rapid accelerator response will help you win, while on city streets, it will realize a comfortable and long drive in addition to low fuel consumption. Specifications Include Terminal A terminal nut is attached that fits with most of the world's spark plug cables. Please remove the nut for installations that do not require one. (The terminal nuts on the IWM and IK-G types are solid parts and cannot be removed.) Built-in, Highly Reliable Resistor All IRIDIUM POWER plugs include a highly reliable, 5,000 ohm monolithic resistor specification to reduce electromagnetic noise that may affect electronic devices. (For all plug types) Highly Corrosion Resistant, Burnished Nickel Plating The plug housing is plated with burnished nickel, the same as plugs used for racing. It is highly resistant to corrosion and rust even while touring in continually rainy weather and during motocross events. (Low-heat range types excluded) 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. (Only with: IU31, IUH24, IUH27, IX22, IX24, IX27, IUF22, IUF24, IWF22, IWF24, IWF27, IW24, IW27, IW29, IW31, and IW34) 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. (excluding IUF27A, IUF31A, IU24A, IU27A, IU31A, IY24, IY27 & IY31) U-Groove Ground Electrode The 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. (excluding IUF27A, IUF31A, IU24A and IU31A) 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. (For all plug types) 0.4 mm Diameter Iridium 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. Moreover, the special iridium alloy used was developed by DENSO with the following patented processes (for all types): Japan (2877035, 2921524, 3000955), U.K. (2302367), U.S.A. (5977695, 6078129, 6093071, 6094000, 6262522), People's Republic of China (961022841), Republic of Korea (0292083). 360 Laser Welding The process used to mount the iridium tip is a highly reliable "All-around Laser Welding" process that is able to withstand all kinds of driving conditions.

Quotes will therefore always be for an insured courier, or tracked post, depending on the weight and value of the item. For items that are being sent within the UK via 2nd class post, please allow 3-5 days from the date of dispatch before contacting us. You will usually be advised when items have been dispatched via the EBay email service. Please note that when working out how long it will take for items to arrive, you must add together the time to dispatch and the shipping time, as not all items can be dispatched the same day you order them. We will have entered an approximate dispatch time on each listing. EBay should work out the approximate date of receipt for you, based on both the dispatch time and the delivery time. For all items that are sent via courier, you should be able to track your own parcel using the tracking number that we enter at the point of dispatch Note that for items sent out via courier, all of the following post codes are classes as premium areas, and as such will generally incur a 20 courier charge, instead of the usual UK Mainland Charge.
