NGK V-Power Spark Plugs

NGK V-Power spark plugs offer economical performance for nearly any automotive application—and they're the only plugs with NGK's V-Groove technology. These plugs enhance ignitability, lower the voltage requirements of ignition systems, and have strong anti-fouling characteristics, while improving fuel mileage and acceleration performance. The V-Power plugs are also highly durable against electrical and chemical wear, making them long-life replacement plugs. Because of the V-Groove, the spark occurs at the edge of the center electrode—so heat is not absorbed by the electrode itself. This allows the flame kernel to expand quickly and efficiently for a complete burn and great performance. More than a hundred models are available, both universal and application-specific; order the plugs designed for fitment on your vehicle.

Denso Iridium Power Spark Plugs

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

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

NGK Resistor Spark Plug Wire Sets

NGK Resistor spark plug wire sets utilize a construction method known as "variable pitch" wire winding to create resistance to radio frequency interference. They have a lower resistance than conventional carbon core wires, which translates into longer wire life. At the center of each wire is a fiberglass stranded core, made from the same family of materials as those used in bulletproof vests. This core greatly enhances the overall strength of the wire and prevents the pulling strains that wires are often subjected to. The spark plug wires feature custom-designed terminal boots that provide an exact fit—and high-quality EPDM and silicone coverings to resist high temperatures, oil, and chemical damage. Each wire is fitted with a positive-locking, corrosion-resistant, nickel plated terminal end for a tight fit and maximum resistance to vibration and separation. The wires are numbered to correspond to cylinder numbers, and the coil wires are color-coded for a correct and easy installation. Order the Resistor set designed for your vehicle application.
