PL420 Fuel Filter

JZHILAN PL420 is a high-performance fuel filter specifically engineered for vehicles complying with China’s National V/VI emission standards, designed to support advanced high-pressure common rail systems. As a key component in the fuel supply chain, this filter (produced by Shanghai Jingzhi Blue Filter Co., Ltd.) integrates efficient filtration and water separation functions to protect precision engine parts.

Its core purpose is to remove solid contaminants (such as dust, metal particles, and sediment) from diesel fuel, while also separating moisture that may enter the fuel system—critical for preventing corrosion, injector clogging, and damage to high-pressure fuel pumps (components sensitive to impurities in modern emission-compliant engines). The filter uses high-quality media to ensure consistent filtration efficiency, even under heavy-duty operating conditions (e.g., commercial trucks, construction machinery, or long-haul vehicles).

Notably, it is tailored for National V/VI vehicles, aligning with stricter emission and performance requirements. The product also includes usage reminders: it should be replaced per maintenance schedules, and the entire fuel system should be cleaned when replacing the filter (to maintain optimal performance). By maintaining clean, dry fuel, the JZHILAN PL420 helps enhance combustion efficiency, reduce maintenance costs, and extend the service life of both the fuel system and the engine.
