Bosch S3004 - Air Filter Car

Bosch S3004 Air Filter Car – Engine‑Performance Guardian

The Bosch S3004 is a high‑performance engine air filter designed to protect your vehicle’s combustion system from dust, dirt, and other airborne contaminants. It is engineered for a wide range of BMW models—including the 3 Series, 5 Series, 7 Series, X3, Z3, and Z4—as well as many other cars that require a reliable air intake solution.

Key Features

• Superior Filtration Efficiency: Captures up to 99.9 % of airborne particles down to 0.5 µm, ensuring clean air reaches the combustion chamber.
• High Moisture Resistance: The filter media is engineered for excellent performance in wet conditions, preventing moisture buildup that could compromise airflow.
• Durable Construction: Made from premium cellulose and synthetic fibers that resist tearing and degradation over time.
• Easy Installation: Fits standard air box dimensions (approx. 58 mm height × 178 mm width × 243 mm length) for quick replacement without special tools.
• OEM‑Approved Quality: Meets or exceeds Bosch’s original equipment specifications, guaranteeing compatibility and reliability.

Design & Construction Details

The S3004 employs a multi‑layered media system. The outer layer provides coarse filtration to trap larger debris, while the inner layers use finer fibers for fine particle capture. This layered approach balances airflow resistance and filtration performance, maintaining engine efficiency without sacrificing power.

Its housing is molded from high‑temperature resistant plastic that protects the filter media from heat and vibration. The sealed edges prevent dust ingress, extending service life even in harsh driving environments.

Compatibility Overview

For exact fitment, consult your vehicle’s service manual or the Bosch part number 1457433004.

Installation Guide

1. Locate the Air Box: Open the hood and find the air intake housing.
2. Remove Old Filter: Unscrew or unclamp the existing filter, carefully removing it to avoid contaminating the interior.
3. Clean the Housing: Wipe any dust from the inside of the air box with a dry cloth.
4. Insert S3004: Place the new filter into the housing, ensuring the airflow direction arrow points correctly.
5. Secure and Seal: Reattach clamps or screws. Verify that all seals are tight to prevent leaks.
6. Check for Leaks: Start the engine and listen for any unusual noises indicating a poor seal.

Maintenance Tips

• Inspect the filter every 12,000–15,000 km or after driving in dusty conditions.
• If you notice reduced airflow or increased engine noise, replace the filter promptly.
• Avoid washing the filter with water; it is designed for dry use only. If contaminated, discard and replace.
