Denso Iridium Power spark plugs feature a 0.4mm iridium center electrode and best demonstrate their performance improvement during acceleration. The world's smallest center electrode and specially shaped ground electrode deliver maximum spark energy while withstanding temperatures greater than 4000 degrees F. These features combine to achieve higher ignitability and require lower spark voltage than ever before. As a result, acceleration improves in comparison with normal plugs. To increase ignitability, the flame kernel produced by the spark must be able to grow unobstructed. Normally, this can be accomplished by widening the spark gap. However, this causes spark voltage to increase, which has the opposite effect. Iridium Power plugs use Denso's patented U-Groove ground electrode to achieve maximum ignitability while minimizing required voltage. These spark plugs are available for a wide range of specific applications, including cars, trucks, vans, ATVs, UTVs, scooters, street and off-road motorcycles, personal watercraft, and snowmobiles. Order the model designed for your vehicle. Key features and benefits of Denso Iridium Power spark plugs include: * Patented 360 degree laser-welding assembly process * Unsurpassed center electrode durability * Available for many performance and power sports applications * Improved spark ignition for maximum combustion, even with lean air-fuel mixtures

Denso Iridium TT spark plugs, with their unique Twin-Tip technology, have two "tips": a 0.4mm iridium center electrode, and a 0.7mm platinum ground electrode. First used with OE spark plugs for luxury and performance cars, they are the smallest mass-produced center electrodes available. They require lower voltage and feature high-ignitability, so there is less interference with spark growth (quenching) and the twin tips deliver omnidirectional ignition, unlike the flat "sandwich" ignition of other spark plugs. Denso selected iridium and engineered it with rhodium to build the most durable alloy for spark plugs. Their patented formula has the highest concentration of iridium of any spark plug and even under the most severe engine temperatures resists oxidation and voltage wear for extended periods. The superior ignition of Denso Iridium TT spark plugs means more efficiency, fewer misfires, and significantly improved combustion, optimizing power and fuel economy like never before. Order the model designed for your vehicle application. Additional features of Denso Iridium TT spark plugs include: * Revolutionary 0.4mm center electrode means significantly improved combustion and reduced misfires * Invented by Denso, Iridium TT Twin-Tip technology creates a larger flame front for more complete combustion * Precision 360 degree laser-welding technology ensures structural support for the iridium center electrode, even in the harshest combustion environments * Tested to last well beyond 100,000 miles, with minimal loss of performance, for greater lifetime savings than any plugs available today

Denso standard spark plugs are designed with the smallest details in mind. Case in point: machine-rolled threads to prevent seizing or cross-threading during installation/removal. Each spark plug is 100 percent pre-fired to assure the highest possible quality. The purified alumina powder 5-rib insulator prevents flashover, provides exceptional strength, and significant thermal conductivity. The copper-glass seal cements the center electrode and insulator for a gas-tight bond. Denso standard spark plugs are available with a variety of options—including projected, non-projected, and extended center electrodes, as well as rotary engine versions. Order the model recommended for your specific vehicle and engine size.

Denso U-Groove spark plugs are Denso's "standard" spark plug, but they're still something special. U-Groove plugs employ a unique, channeled ground electrode designed to generate a larger spark nucleus at the point of ignition. Greater spark energy than ordinary plugs means improved flame travel, producing more complete, consistent, and efficient combustion. Denso U-Groove spark plugs are engineered for greater fuel efficiency and improved throttle response. The U-Groove ground electrode was developed to meet OEM's demands for improved ignitability and lower emissions. With the U-Groove, firing can be greatly improved without increasing the spark plug gap. The insulators are made from purified alumina providing support for the center electrode, while preventing flashover and voltage loss. The copper and glass mixture bonds the center electrode together to form a gas tight seal. Select the model and options best suited for your application. Additional features and benefits of Denso U-Groove spark plugs include: * 360 degree laser-welded * 100 percent pre-fired to ensure reliable operation * Copper core center electrode for superior thermal conductivity * Unique 5-rib insulator reduces flashover and decreases voltage loss * Dual copper and glass seal bonds the center electrode and insulator together for a gas-tight seal * Original equipment in many automotive applications * Precision machine-rolled threads reduce seizing and cross-threading in delicate aluminum heads * Wide range of part numbers for thousands of applications, including classic and collector cars * Lasts twice as long as conventional plugs
