Bosch N2855 - Diesel Filter Car

Bosch N2855 Diesel Fuel Filter is a high‑performance component designed to protect your vehicle’s engine by removing contaminants from diesel fuel before it reaches the combustion chamber. This filter is engineered for durability, reliability, and optimal flow characteristics, ensuring that only clean, particle‑free fuel circulates through the injection system.

Key Features

Advanced Filtration Technology: The N2855 employs a multi‑layer filtration media that captures particles as small as 1 micron. This level of precision prevents wear on injectors and maintains engine efficiency over extended periods.

Robust Construction: Made from high‑grade polypropylene, the filter housing resists corrosion and chemical attack from diesel additives. The reinforced gasket seals provide a leak‑free seal under high pressure.

Optimized Flow Rate: With a flow resistance of only 0.5 psi at full capacity, the N2855 delivers ample fuel throughput for both light‑weight and heavy‑duty engines without compromising filtration performance.

Easy Installation: The filter’s standard dimensions (outer diameter 93.5 mm, height 120 mm) match a wide range of OEM specifications. A quick‑release clamp system allows for rapid replacement during routine maintenance or in emergency situations.

Compatibility

The Bosch N2855 is specifically engineered to fit the fuel systems of several high‑performance vehicles. It matches the original equipment specifications for:

• Porsche Cayenne 92A (3.0 L Diesel)
• Volkswagen Touareg (7P5, 7P6) 3.0 L Diesel
• Other diesel‑powered models that require a 93.5 mm diameter filter with a 120 mm height.

Performance Benefits

Engine Protection: By trapping fine particulates, the N2855 prevents abrasive wear on fuel injectors and pumps, extending component life and reducing maintenance costs.

Fuel Efficiency: Clean fuel flow reduces friction within the injection system, allowing the engine to operate at peak efficiency. This can translate into measurable improvements in fuel economy.

Reduced Emissions: Consistent delivery of clean diesel helps maintain optimal combustion conditions, which can lower exhaust emissions and support compliance with stringent environmental regulations.

Installation Guide

1. Safety First: Disconnect the battery and relieve fuel system pressure before beginning work.
2. Remove Old Filter: Unscrew the existing filter housing, allowing any residual fuel to drain safely. Dispose of the old filter according to local regulations.
3. Prepare New Filter: Remove protective seals from the N2855 and inspect the gasket for damage. Apply a thin layer of diesel-compatible lubricant to the gasket edges if recommended by Bosch guidelines.
4. Install: Place the new filter into the housing, ensuring proper orientation. Tighten the clamp or bolt to the manufacturer’s torque specification (typically 12–15 Nm).
5. Re‑pressurize System: Reconnect the battery and allow the fuel system to pressurize. Check for leaks around the new filter installation.
6. Test Drive: Conduct a short test drive, monitoring engine performance and listening for any abnormal noises that might indicate improper seating or blockage.

Maintenance Tips

While the N2855 is designed for long service life, regular inspection can preempt potential issues:

• Visual Check: Inspect the filter housing for cracks or deformation after every 10,000 km.
• Pressure Test: Verify that fuel pressure remains within OEM specifications during operation.
• Replacement Interval: Replace the filter at least once every 30,000 km or sooner if operating in high‑dust environments.
