NGK Laser Iridium spark plugs feature laser-welded technology. Lasers are used to pinpoint precision welds, reducing excess debris; this decreases the required voltage to bridge the spark gap. An iridium disc is welded on the center electrode and a platinum disc is welded on the ground electrode, reducing the wear rate of both surfaces and ensuring great durability and long life. These spark plugs are available for use with a variety of engine types.

Featuring one of the strongest available materials for this type of product, APR Iridium Pro spark plugs help provide an ideal upgrade for tuned engines. They run cooler, resist pre-ignition, last longer than other materials with higher melting points, and require less voltage to produce a strong spark. The electrode is harder and stronger than other materials; can dissipate heat more easily; and is better protected from melting, cracking and other limitations found with standard models. These plugs are designed for use on tuned and high-performance vehicles that benefit from a 'cold' plug. They also pair nicely with APR ignition coils, where applicable. Order the APR Iridium Pro spark plugs recommended for your vehicle. Other features include: * Heat range 9 (similar to Bosch 3, Brisk 10, Denso 27, and NGK 9 ranges) * Melting point is higher than platinum (38 percent), copper (125 percent) and silver (152 percent) * Available in non-projected and projected insulator designs * Optimized electrode design for hard-to-ignite fuels (ethanol, etc.)

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
