Bosch S0508 - Air Filter Car

Product Overview

The Bosch S0508 Air Filter Car, also catalogued as BOSCH F 026 400 508, is a high‑performance air intake filter engineered for modern automotive engines. Designed with precision, it delivers superior filtration efficiency while maintaining optimal airflow to the combustion chamber.

Key Features

• Advanced Filtration Technology: Utilises multi‑layer media that captures fine particulates down to 0.3 microns, protecting engine components from dust, pollen, and road debris.
• Optimised Airflow: Engineered with a 37.3 mm diameter opening, the filter allows maximum air volume, enhancing fuel economy and power output.
• Durable Construction: Constructed from high‑grade synthetic fibers and reinforced housing to resist moisture absorption and extend service life.
• Easy Installation: Designed for quick fitment; no special tools required. The filter’s shape matches the OEM cavity, ensuring a snug seal.
• Compatibility with Multiple Models: Specifically tailored for a range of BMW vehicles, including 6‑Series Gran Coupé, 3‑Series Sedan, and 5‑Series Sedan models.

Compatibility & Fitment

The Bosch S0508 is engineered to fit the following vehicle families:

• BMW 6 Series Gran Coupé (E63/E64)
• BMW 3 Series Sedan (E90/E92/E93)
• BMW 5 Series Sedan (E60/E61)

Its dimensions—37.3 mm diameter and a precise cartridge length—ensure a perfect match with the OEM air intake housing, providing a seal that prevents unfiltered air from entering the engine.

Installation Guide

1. Prepare the Vehicle: Park on level ground, engage the parking brake, and allow the engine to cool. Open the hood and locate the existing air filter housing.
2. Remove Old Filter: Unscrew or unclip the housing cover, gently lift out the old filter cartridge, and discard it responsibly.
3. Inspect Housing: Clean any debris from the intake duct and ensure the gasket area is free of oil or dirt.
4. Insert New Filter: Place the Bosch S0508 into the housing, aligning the cartridge with the airflow direction indicated by the arrow on the filter. The filter should sit flush against the housing walls.
5. Secure Housing Cover: Reattach the cover and tighten all fasteners to the manufacturer’s torque specifications.
6. Verify Seal: Inspect for any gaps or loose fittings that could allow unfiltered air to bypass the cartridge.

Maintenance & Longevity

The Bosch S0508 is designed for long‑term use, but regular inspection ensures peak performance:

• Check Frequency: Inspect the filter every 10,000 km or at least twice a year, depending on driving conditions.
• Cleaning Procedure: If the filter appears lightly clogged but still functional, gently vacuum the surface. Avoid washing with water to preserve the media integrity.
• Replacement Interval: Replace the cartridge after 30,000 km or when airflow resistance is noticeable, as indicated by a decline in engine responsiveness.

Performance Benefits

Installing the Bosch S0508 Air Filter Car yields tangible advantages for vehicle performance:

• Enhanced Fuel Efficiency: By maintaining optimal airflow, the engine can operate at its most efficient combustion ratio.
• Improved Engine Longevity: The filter’s high‑efficiency media protects pistons, valves, and fuel injectors from abrasive particles.
