Denso Iridium Racing spark plugs are elite spark plugs for the serious racer that best demonstrate their performance improvement during acceleration. Their 0.4mm iridium-rhodium alloy center electrodes require less voltage to fire (up to 5,000 V less) and produce the hottest, most concentrated spark. Plus, 100 percent pure platinum 0.8mm ground electrodes reduce the risk of melting during harsh racing conditions. Through superb ignition performance and spark voltage, non-firing and misfires under a variety of conditions are greatly reduced. As a result, combustion conditions are improved dramatically, increasing engine output for the ultimate in power and torque, as well as increased engine efficiency. These spark plugs are a popular choice for street and off-road motorcycles, scooters, ATVs, UTVs, snowmobiles, personal watercraft, and more. Order the model designed for your specific application. Key features and benefits of Denso Iridium Racing spark plugs include: * Almost all Iridium Racing plugs contain a monolithic resistor that blocks noise that may affect electronic devices * Burnished nickel plating on the housing for corrosion resistance; thinner on the threads to reduce head damage * To withstand severe conditions, a patented 360 degree laser welding process secures the iridium tip * Between the center electrode and insulator, a patented spark cleaning pocket burns off carbon, restoring electrical resistance * 20 percent stronger insulator * Silicone coated insulator surface is isolated from moisture and carbon, preventing a decrease in resistance * Ground electrode is welded on and gapped without any bending, reducing residual stress and increasing durability * Enlarged housing end-face chamfer allows slight tuning inaccuracies, improves self-cleaning, and prevents fouling * Durable, reusable packaging protects spark plugs when not in use * Handles extreme compression and boost levels * Maximizes track time, minimizes downtime * Delivers maximum spark energy * Withstands temperatures greater than 4000 degrees F

Denso alternators are not only original equipment on many of the world's top production cars; they are a favorite in motorsports as well, where their light weight, high-efficiency, and durability make them the natural choice. Denso remanufactured alternators go through a grueling process; stators and rectifiers are tested to 300 V, while rotors are submitted to 600 V, to ensure reliable performance. Rotor slip rings are buffed to an 8 micron surface finish, with run out limited to 20 microns, minimizing brush wear and abrasion. Bearings are validated to OE standards and loaded with premium OE-specification lubricants. Offered in wide range of amp ratings for hundreds of specific vehicle applications, all alternators meet Denso's rigorous First Time Fit standards. Contemporary vehicles employ dozens of sophisticated electronic systems, placing heavy demands on the charging system. The alternator is no place to cut corners. Additional features of Denso remanufactured alternators include: * Meet or exceed all manufacturer standards, and provide years of reliable service * First Time Fit provides perfect mounting with no belt/pulley alignment issues * Housings re-tapped and damage-checked for heat warping, corrosion, or improper surface alignment * Voltage regulators 100 percent tested to OE standards * All hardware stripped and replated * Premium cores and precise OE-assembly benchmarks * Designed to meet grueling heat and electrical requirements * OE-quality fit and appearance * Full compatibility with sensitive electronics systems

The manifold absolute pressure (MAP) sensor is part of many engine electronic control systems. It delivers instantaneous manifold pressure information to the engine's electronic control unit (ECU). The data provided by the MAP sensor is used to calculate air density and determine the engine's air mass flow rate. This data determines the required fuel metering and ignition timing for optimum engine performance. Denso manifold absolute pressure sensors provide superior air and fuel regulation with leading edge sensing technology. As one of the first companies to produce engine management sensors, Denso continues to bring new technology to the industry. Key features of Denso manifold absolute pressure sensors include: * Meets or exceeds OEM specifications * Manufactured with the highest quality materials * Efficiently measures the pressure of the intake manifold * Engineered to fit the first time * Enhances performance and fuel economy by replacing a failing MAP sensor

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
