Red Line Water Wetter Cooling System Treatment

Red Line created the industry of pushing bubbles out of the way to ensure cooling with their Water Wetter cooling system treatment. It's a unique agent for cooling systems that doubles the wetting ability of water. It offers rust and corrosion protection that allows for use of straight water in racing or reduced antifreeze levels in warm climates. It also improves heat transfer and reduces cylinder head temperature. Help your engine keep its cool with Red Line Water Wetter cooling system treatment. Instructions and specs: * Use 1 bottle for most passenger cars and light trucks—treats 3 to 5 gallons or 13.2 to 15.9 liters * Use 2 bottles with larger cooling systems * Use 1 oz. (3 to 4 capfuls) per quart for small cooling systems * Compatible with new or used antifreeze (including those with DEX-COOL and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems * Satisfies ASTM D2570 and ASTM D1384 corrosion tests for glycol-based antifreezes * Contains no ethylene glycol

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.

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.
