Audi RS4 B8 RS5 8T Oil Sump Pump Motor 4.2 Petrol CFSA CFS 079115216G

Audi RS4 B8 RS5 8T Oil Sump Pump Motor 4.2 Petrol CFSA CFS is an original lubrication system component designed for V8 petrol engines, engineered by the manufacturer to ensure stable oil pressure under dynamic driving conditions. Thanks to its factory design, the pump works seamlessly with the stock oil pan and lubrication channels, ensuring predictable engine behavior at high RPMs. This is a solution for users who expect a reliable, technically matched part rather than universal aftermarket replacements.

Purpose and role in the 4.2 engine

The presented oil pump has been developed for high-power petrol engines, where stable lubrication under heavy load is crucial for the durability of the bearings, crankshaft, and timing system. The pump's construction is adapted to the characteristics of 4.2 units, which often experience high rotational speeds and prolonged thermal loads. The original geometry of the channels and rotors allows for maintaining proper oil flow both at idle and at maximum load, which reduces the risk of pressure drops in critical points of the system. For cars driven dynamically, this means more predictable engine operating conditions and a lower risk of costly failures.

Construction and fitment to the lubrication system

The pump is an integrated component of the lower engine assembly, working with the factory oil pan and oil pickup. Precise fitment with the engine block and accessories facilitates installation and reduces the need for additional modifications. By maintaining the original design, the correct oil suction geometry from the pan is preserved, which is significant during rapid acceleration and braking. This solution is particularly important in petrol units, where oil temperature can rise quickly and its viscosity changes over a wide range. The properly selected pump drive ratio and its efficiency allow for maintaining lubrication parameters within the limits specified by the vehicle manufacturer.

Benefits of using an original oil pump

Using a factory oil pump in a V8 petrol engine provides a number of practical technical benefits:

• maintaining oil pressure characteristics in accordance with the manufacturer's design,
• compatibility with the stock oil pan and lubrication channel system,
• reducing the risk of insufficient lubrication at high RPMs and heavy loads,
• easier diagnostics – operating parameters correspond to factory reference values. For users who drive their cars dynamically, the repeatability of lubrication system operating parameters is also important, which facilitates monitoring the engine's condition and planning further modifications.

Condition, verification, and installation recommendations

The item comes from disassembly and is offered as a used part, which allows for an economical repair of the lubrication system while maintaining the original design. Before installation, a standard workshop procedure is recommended: thorough cleaning, checking operating clearances, and verifying the seats and surfaces mating with the engine block and oil pan. To fully utilize the pump's potential, it is worth combining its installation with an oil change to the specification recommended by the manufacturer and checking the condition of other lubrication system components, such as the oil pickup, seals, and return channels. This approach increases the chance of stable and long-lasting engine operation after the repair is completed. If you are planning a comprehensive repair or upgrade of the engine area in your Audi and need other components from the same group, such as housings, covers, or seals related to the lubrication system, check out the available parts in the Audi Oil Pans category.

Additional information for sports car users

Owners of powerful Audi models often combine the replacement of lubrication system components with performance-enhancing modifications. In such cases, it is particularly important that the oil system is maintained in good technical condition and based on proven, factory solutions.
