ST 342 Fuel Filter (Flow-through, with quick-release couplings)
This filter is designed for gasoline injection systems that require reliable fuel filtration under pressure. The snap-in system allows for easy replacement without the need for special tools or clamps.

Key Features:
Corrosion-Resistant Housing: Made of aluminum alloy or steel with a protective coating, preventing rust from contact with road reagents and moisture.

Highly Efficient Filtration: A multi-layer paper curtain with a special impregnation traps microparticles of contaminants, protecting the injector nozzles from clogging and wear.

Stable Pressure: The filter's internal geometry minimizes fuel flow resistance, ensuring smooth engine operation at high revs.

Reliable Fittings: The inlet and outlet design accommodates standard fuel valves, ensuring the absence of fuel leaks even with sudden pressure changes in the system.

Applicability (Wide Coverage):
The ST 342 model is one of the most versatile in the gasoline vehicle segment:

OPEL: Astra (G, H), Corsa (C, D), Vectra (B, C), Zafira (A, B) — since 1995

DAEWOO: Lanos, Nexia, Nubira, Leganza — since 1997

VOLKSWAGEN: Polo (sedan/hatchback), Golf IV, Bora, New Beetle.

VOLVO: S40, V50, C30 — since 2004

CHEVROLET: Aveo, Lacetti, Spark

ŠKODA: Fabia, Octavia Tour

Technical Parameters:
Type: Flow-through filter

Fastening Type: Quick-release fittings

Outer Diameter: ~55–60 mm

Technical note:
Replacing the ST 342 filter is recommended every 20,000–30,000 km. Using a clean filter not only extends the life of the fuel pump but also reduces fuel consumption due to proper injector spray pattern.
