PL421 Fuel Filter

The PL421 Fuel Filter is a high-performance filtration component tailored exclusively for vehicles complying with China’s National V/VI emission standards, optimized for modern high-pressure common rail systems. As a "medium filtration and separation technology expert," it safeguards critical fuel system parts (like injectors and high-pressure pumps) by efficiently capturing solid contaminants (dust, metal particles, sediment) and separating moisture from diesel fuel—key to preventing corrosion, clogging, and premature component damage.

Constructed with premium filtration media and a durable, industry-standard structure, the PL421 delivers consistent reliability even under heavy-duty operating conditions (e.g., commercial trucks, construction machinery, long-haul fleets). It is compatible with part numbers VG1092080052 and 1105050C50A, and requires diesel fuel meeting GB19147 (National V/VI) standards; prompt replacement is recommended when system alerts indicate filter clogging.

By maintaining clean, dry fuel flow, the PL421 enhances combustion efficiency, reduces unplanned maintenance downtime, and extends the service life of fuel system components—making it a cost-effective choice for global fleet operators and equipment owners prioritizing performance and durability for National V/VI-compliant vehicles.
