Original MANN-FILTER Oil Filter WK 612/5 – For passenger cars

MANN‑FILTER Oil Filter WK 612/5

The MANN‑FILTER Oil Filter WK 612/5 is a high‑performance filtration solution designed specifically for passenger cars. It delivers reliable protection for the engine’s lubrication system, ensuring that only clean oil circulates through critical components such as pistons, bearings, and camshafts.

Key Features

• Advanced Filtration Technology: Utilizes a multi‑stage filter media that captures particles as small as 0.5 µm, preventing wear and extending engine life.
• High Flow Capacity: Engineered to maintain optimal oil pressure, even under demanding driving conditions, thanks to its low resistance design.
• Durable Construction: Made from high‑quality polypropylene housing that resists corrosion and temperature extremes.
• Universal Fit: Compatible with a wide range of passenger car models, making it a versatile choice for mechanics and DIY enthusiasts alike.
• Easy Installation: Features a standard threaded connection (M20x1.5) that fits most OEM oil filter mounts without modification.

Performance Benefits

The WK 612/5 filter is engineered to keep the engine’s lubrication system free from contaminants, which offers several tangible advantages:

• Engine Longevity: By trapping dirt and metal particles, it reduces internal wear, thereby extending the service life of critical components.
• Fuel Efficiency: A clean oil flow improves combustion efficiency, potentially leading to better fuel economy.
• Reduced Maintenance Intervals: The filter’s long‑life media allows for extended intervals between changes without compromising protection.
• Consistent Oil Pressure: Maintains steady pressure across the engine, ensuring that all moving parts receive adequate lubrication.

Installation Guide

1. Preparation: Warm the engine to operating temperature to allow oil to flow freely. Drain a small amount of oil if necessary to prevent overflow during filter removal.
2. Remove Old Filter: Use an appropriate wrench or filter socket to unscrew the existing filter. Be prepared for residual oil; keep a rag nearby.
3. Inspect Mounting Surface: Clean any debris from the mounting flange and ensure it is free of cracks or damage.
4. Apply Sealant (Optional): Some users apply a thin layer of factory‑approved sealant to the threads for an extra leak‑proof seal, though many find the filter’s built‑in gasket sufficient.
5. Install WK 612/5: Thread the new filter onto the housing clockwise until snug. Tighten by hand and give a final quarter turn with a wrench—over‑tightening can damage the gasket.
6. Check for Leaks: Start the engine, let it reach operating temperature, and inspect the filter area for any signs of oil leakage.

Compatibility Overview

The WK 612/5 is designed to fit a broad spectrum of passenger cars. While specific model compatibility varies by manufacturer, common vehicle families that accept this filter include:

• Compact and sub‑compact sedans from major OEMs.
• Mid‑size family cars with inline‑4 engines.
• Light commercial vehicles that share the same engine architecture as passenger models.

For precise fitment, consult your vehicle’s service manual or a trusted parts database. The filter’s standard dimensions (114 mm diameter, 5 mm thickness) make it a reliable choice for many engines.

Maintenance Tips

• Replace the filter at every oil change to maintain optimal protection.
• Avoid using incompatible oils; always follow the manufacturer’s viscosity recommendations.
• If you notice a sudden drop in oil pressure or engine noise, inspect the filter for clogging or damage.
