EE 337 Fuel Filter

EE-337 High-Efficiency Fuel Filter (Replaces 1-457-434-310)

Protect your diesel engine’s sensitive injection system with the EE-337 Fuel Filter. This premium spin-on filter is designed to replace the industry-standard Bosch 1-457-434-310 (N4310), offering superior water separation and particle filtration for modern Common Rail Diesel (CRDi) engines.

As diesel fuel can contain microscopic contaminants and water, the EE-337 ensures that only clean, moisture-free fuel reaches your engine. This prevents fuel pump wear, injector clogging, and costly engine downtime.

Key Performance Features:

• Precision Filtration: Engineered to capture contaminants as small as 2–5 microns, protecting high-pressure fuel components.

• Water Separation: Effectively removes water from fuel to prevent corrosion and microbial growth in the fuel system.

• Durable Build: Features a heavy-duty steel canister and high-quality seals to withstand the high pressures of modern diesel systems.

• OE-Match Fitment: Designed for a seamless install with standard M16 x 1.5 inlet and M12 x 1.5 outlet threading.

Verified Compatibility & Cross-Reference

The EE-337 is a versatile replacement part used across major European, Asian, and American diesel vehicle brands.
