Red Line MT-90 Transmission Gear Oil

Red Line MT-90 transmission gear oil is designed to provide excellent protection and improved shiftability for manual transmissions and transaxles. Popular in Nissan, Toyota, and Mazda manual transmissions and transaxles, as well as other selected applications, this is a 75W90 GL-4 gear oil that's slightly heavier than MTL. It provides excellent protection of gears and synchronizers, and its balanced slipperiness provides a perfect coefficient of friction, allowing for quicker shifting.

Motorcraft Oil Filters

Motorcraft oil filters are specifically designed for Ford, Lincoln, and Mercury vehicles. Each filter, including the popular Motorcraft FL-1A, uses as many as 12 high-quality components. Choose the style designed for fitment on your vehicle. Construction features include: * Steel cases: "Ironed" for a precise fit, fluted to ease removal, and painted for rust resistance * Pressure relief valve: When it's cold outside, or if the filters become clogged, oil flow through the filters can be reduced. If this happens, the relief valve opens to provide a continuous oil supply. Its design also minimizes the chance of contaminated oil recirculating back * Anti-drainback valve: This feature keeps oil in the filters to prevent "dry starts" after your engine has been turned off. It's made with specially formulated materials that resist the aging effects that an engine's heat can cause * Efficient filter media: Re-engineered media increases Motorcraft filters' dirt-collecting capabilities, allowing them to capture more engine-harming particles than ever before

Fel-Pro PermaTorque Head Gaskets

Fel-Pro PermaTorque head gaskets are the industry standard for no-retorque designs available today. The torque retention is gained through premium materials comprising four distinct components--core, facing, coating, and armor--and the process used in the manufacture of the gaskets. Fel-Pro PermaTorque head gaskets have been proven to retain the highest torque retention significantly better than other brands. These composite-style gaskets compress at installation to conform to and seal minor surface imperfections, while retaining the ability to resist or recover from compression during engine operation. The result is a clamping force and a secure seal over a long period of time--without retorquing.
