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.

Autolite Copper Core Spark Plugs

Autolite copper core spark plugs feature a cold-formed steel shell with precision-rolled threads, a full copper core electrode for better performance, and a one-piece terminal post to add strength. The ignition plugs use a copper-glass seal that bonds the insulator and terminal post center electrode together. This ensures full voltage at the spark gap and a 100 percent leak-proof, gas-tight seal. Autolite features an extensive application guide to cover just about everything with an internal combustion engine. Keep your engine running smoothly and reliably with Autolite replacement copper core spark plugs.

NGK Laser Platinum Spark Plugs

These double platinum NGK laser platinum spark plugs feature laser-welded technology. Lasers are used to pinpoint precision welds, reducing excess debris. The reduction of debris decreases the required voltage to bridge the spark gap. Platinum disks welded on the ground and center electrodes reduce the wear rate on both of these surfaces, ensuring great durability and long life.

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

Champion Double Platinum Power Spark Plugs

Champion Double Platinum Power spark plugs have platinum on both the center and ground electrodes for longer life with minimal wear. The center electrode is platinum fine wire that's riveted onto the nickel alloy center electrode—and the ground electrode has a pad welded to the surface. These spark plugs use a fine-wire and V-trimmed center electrode to create a sharper spark focus than conventional plugs. With their exclusive Heat-Active alloy, they reach operating temperatures quickly and maintain stable temperatures under varying engine loads. Widely designed for distributor-less ignition systems, Champion Double Platinum Power spark plugs can maximize fuel efficiency and spark energy.
