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.

Question: Can you run regular gear and axle oil with a limited-slip? You could answer "No" and be correct—or you could say, "Yes, but you'll need to add Yukon Gear & Axle friction modifiers." Clutch-type limited-slips can be as chatty as a room full of lawyers, and just as dangerous. When added to gear oil, this modifier helps the clutches and improves differential noise while extending life. Limited-slips have a lot of moving parts; keep them in shape with Yukon Gear & Axle friction modifiers.

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.
