Womala Oil Filter Housing Assembly OE 30788494 Oil Filter Rack for Auto Parts S40

Oil Filter Housing Assembly (Oil Filter Rack) (OE: 30788494)

The Oil Filter Housing Assembly (also referred to as the Oil Filter Rack, OE Number: 30788494) is a critical component in the lubrication system of the Auto Parts S40 T5, designed to house and secure the oil filter while facilitating efficient oil flow between the engine and the filter.

Constructed from high-grade aluminum alloy with a precision-machined sealing surface, this assembly combines lightweight properties (reducing overall engine weight) with exceptional heat resistance (withstanding oil temperatures up to 150°C). Its robust design includes integrated mounting points and a built-in gasket groove, ensuring a tight seal to prevent oil leaks—a common issue with worn or low-quality housings.

Engineered specifically for the S40 T5's turbocharged engine, it accommodates the model's unique oil pressure requirements (up to 5 bar) and filter specifications, making it a reliable OE-grade replacement.

• Filter Securement: Provides a stable housing for the oil filter, ensuring it remains properly aligned with the engine's oil passages during operation—critical for consistent filtration.
• Oil Flow Regulation: Channels pressurized oil from the engine into the filter and back to the engine, with internal passages optimized to minimize pressure drop (≤0.5 bar) and maintain steady lubrication.
• Leak Prevention: Features a precision-machined flange and compatible gasket (often included) that create a tight seal between the housing and engine block, preventing oil leaks that could lead to engine damage or oil loss.
• Heat Dissipation: Aluminum construction aids in dissipating heat from the oil, helping to maintain optimal oil viscosity and extend the life of both the oil and engine components (e.g., bearings, turbochargers in the S40 T5).

This oil filter housing assembly is exclusively designed for:

As a direct OE replacement, it fits seamlessly into the S40 T5's engine bay without modifications, ensuring proper integration with the oil lines and filter. Regular inspection of the housing's seal and threads is recommended to prevent leaks and maintain the engine's lubrication efficiency.
