The ST 500 fuel filter is designed to ensure maximum fuel purity for 2.4-liter (2AZ-FE) and 3.5-liter (2GR-FE) engines. When used with locally produced fuel, the filter effectively traps resins, solids, and condensate, protecting the precision injectors of the fuel injection system.

Pressure Stability: A clogged filter causes the fuel pump to overwork. The ST 500 restores normal system pressure, extending the life of the pump.

Resolving "Dips": If your car begins to jerk during acceleration or has difficulty starting from cold, replacing the ST 500 filter is the number one solution.

Catalytic Converter Protection: The correct mixture (thanks to a clean filter) ensures complete fuel combustion, preventing melting of the expensive catalytic converter.
