For drivers who are particular about driving Iridium Power has been carefully selected for its material and shape to improve ignitability. It provides a stable and high response even under various driving conditions, improving the acceleration and torque of your car.

Features 0.4mm diameter ultra-fine iridium alloy center electrode The tip of the center electrode is made extremely thin using DENSO's proprietary iridium alloy.Reduces ignition voltage and improves ignition performance.

U-groove ground electrode (U-GROOVE) A U-shaped groove is used inside the ground electrode.Achieves excellent ignition performance while keeping spark voltage low.

Tapered cut ground electrode (TAPERED CUT) Cut the tip of the ground electrode into a tapered shape.Smoothes the flow of air-fuel mixture, reduces flame-extinguishing effect, and improves ignition performance.

power up The thinner the center electrode, the better the ignition performance of a plug.Increased power with the adoption of a 0.4mm diameter ultra-fine center electrode.This will appear in the time as a difference in acceleration.

Increase fuel efficiency The 0.4mm diameter ultra-fine center electrode provides stable ignition even when idling, improving fuel efficiency.Greatly brings out the performance of the engine.

Unparalleled ignition power DENSO's unique U-groove grounding electrode provides excellent ignition performance while keeping spark voltage low. This special shape increases the area that comes in contact with the air-fuel mixture, and also grows the flame kernel created by flying sparks, producing a large amount of ignition energy.

Acceleration up The 0.4mm diameter iridium center electrode and specially shaped ground electrode provide high ignition performance and low spark voltage. It achieves high response with fewer misfires in areas with high spark voltage and areas where ignition is difficult.

Output up Low spark voltage and high ignition performance reduce misfires and ignition errors in various operating ranges.Achieves high power with ideal fuel efficiency cycle.Engine output increases.

IW series Fully threaded type with M14 x L19mm.IW16 to 22 are designed to suit the usage environment, with project 1.5mm emphasizing ignitability, and IW24 to 34 emphasizing heat resistance, project -1.5mm. IW24-34 utilizes the high heat resistance of iridium electrodes, and the spark position is 0.5mm more protruding than the standard type (1.0→1.5mm).Ignition performance is improved by adopting a 0.4mm diameter iridium center electrode.

Before purchasing, please check the vehicle model, engine model, drive system, year, grade, etc. with the vehicle inspection certificate and caution plate, and be sure to check the manufacturer's website to see if there are any errors in vehicle compatibility.
