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.

NGK Iridium IX Spark Plugs
NGK Iridium IX spark plugs feature an ultra-fine center electrode that's designed just thick enough to ensure the maximum durability and life of the spark plugs—and just thin enough to create an accurate and consistent spark. They represent the ultimate evolution of spark plug technology and performance. Iridium is the hardest metal used in spark plugs today—six times harder than platinum. This allowed NGK engineers to reduce the voltage requirement for a spark. Iridium IX plugs are available in more than a hundred configurations for universal and vehicle-specific applications.

Sealed Power Engine Assembly Prelubes
Sealed Power engine assembly prelubes have been proven effective by more than 30 years of use on the assembly lines of U.S. car, truck, and off-road engine manufacturers. They are formulated especially for prelubrication of camshaft lobes and lifters (mechanical and hydraulic) prior to engine oil circulation. Also recommended for bearings, valve stems, rocker arms, push rod tips, and other metal-to-metal contact areas within the engine. Prelube increases load-carrying capacity of the engine oil during break-in to prevent scuffing and galling. The prelubes have special additives which withstand the extreme pressures exerted on cams and lifters. These easy flowing petroleum based lubes function as oil additives, which will not affect oil viscosity. They also hold fast to surfaces on which they are applied and won't run off like engine oil, even after prolonged storage time.

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
