The Cooper/Wesfil WZ434 is a lightweight in-line fuel filter built to OEM specifications and cross-referenced to Z434. Encased in a clear plastic housing, it enables quick assessment of fuel cleanliness and clogging. Equipped with effective micro-filtration media, the WZ434 removes rust, dirt, and debris before entering the engine, helping preserve injectors and fuel pumps. It offers a direct replacement solution for vehicles such as the Ford Laser and Mazda 323 (1.6 L) from late 1980s–mid-1990s.

Features:

• Transparent plastic housing for immediate visual monitoring.
• Compact inline form factor suitable for tight engine spaces.
• High-efficiency filter media captures harmful particles before they reach fuel components.
• OEM cross-reference Z434 ensures perfect compatibility with targeted Ford/Mazda models.
• Durable and corrosion-resistant design, yet lightweight.
• Tool-free installation: simply cut the fuel line, install the filter, secure with clamps.
