Bosch 77017WS Diesel Fuel Filter

The Bosch 77017WS diesel fuel filter protects the injection system and engine against environmental particles that can be harmful to components of the fuel system. These particles can include water, dirt and other residue in the fuel that could cause damage to expensive fuel injection components and reduce engine performance.

Advanced Filtration Technology:

• Filters down to as low as 6.5 microns to protect expensive fuel injection components from damaging foreign particles
• 99% filtration rate using premium-quality materials and modern production methods
• Multilayered filter media with high dirt holding capacity of 15 grams to trap and hold harmful particles
• Reduces the chance of premature wear to cylinder walls, pistons, rings, and more

Quality Engineering:

• Designed as a direct OE replacement, ensuring precision fit in the original location
• Correctly sized input and output ports for simple, hassle-free installation
• Engineered using premium quality materials, modern production methods, and expertise with fuel injection systems
• Robust housing designed to withstand high pressure and harsh driving environments

A restricted or clogged fuel filter can result in erratic performance, poor gas mileage and in some cases, complete engine shutdown. Fuel filter replacement at manufacturer-specified intervals will maintain vehicle performance and prolong the life of the engine. Unimpeded fuel flow, provided by a fresh fuel filter, ensures your vehicle performs its best in a wide variety of driving conditions, while extending fuel pump life and improving overall fuel system health.
