1998 Audi A4 Air Filter Hengst

Hengst Filters
Hengst is a leading German OE manufacturer of automotive oil, fuel, air and cabin filtration systems.
Hengst Oil Filter

Hengst oil filters effectively clean the circulating oil of dust, metal particles, soot particles and miscellaneous contaminants. Only clean oil reaches the lubrication and bearing points. Hengst oil filters are also characterized by resistance to high temperatures extreme mechanical long-term stability against sudden changes in pressure and resistance to aggressive components in the oil, thereby fully satisfying the ever-evolving demands for use in advanced modern engines.

Only the latest generation of filter media are used, with added synthetic fibers, impregnation and high filtration grades with a large dirt-holding capacity. Additional characteristics are high-quality seals and gaskets as well as a secure and reliable connection between the seal, end cap and filter paper.

Spin-On Type Oil filters

Hengst spin-on oil filters are made of a sheet steel housing with a pressure-tight crimped screw-on plate that contains the filter element. Changing the filter requires replacing this entire system.

Spin-on oil filters have a filter bypass valve that guarantees a sufficient oil supply for cold starts and very dirty filters that are long past their specified replacement point. In these cases, the unfiltered motor oil is fed through the open valve back into the oil circulation system.

The check valve prevents the oil filter from running empty when the engine is shut off.

• Resistant to high temperatures.
• Extreme mechanical long-term stability against sudden changes in pressure.
• Only the latest generation of filter media is used, with added synthetic fibers, impregnation and high filtration grades with a large dirt-holding capacity.
• High-quality seals and gaskets as well as a secure and reliable connection between the seal, end cap and filter paper.

High-quality Hengst oil filters guarantee a supply of clean oil under all operating conditions, thereby creating the basic conditions for optimum engine performance and operational reliability with longer and longer service intervals.

Warranty Information: 12 month - 12,000 mile limited warranty against defects in material and workmanship.

Hengst Cartridge Oil Filter

Canister Type Oil Filter Kit
The canister type oil filter kits are part of Hengst’s environmentally friendly and easy-to-service ENERGETIC®  concept. For service, only the filter insert needs to be replaced. The valves, screw-on cover and the aluminum housing that contains the oil filter insert remain on the engine block for their entire service life.

Unscrewing the cap opens the automatic drain valve and the dirty oil flows through a separate channel directly into the oil pan. The clipped-on filter insert is then extracted from the housing quickly and easily, without the service technician ever having to come into contact with the oil.

The filter inserts are characterized by high filtration grades and operational reliability. Long service intervals significantly reduce service costs. The use of recycled materials also makes it possible to dispose of the pure-grade filter inserts economically and ecologically by incineration.

• Resistant to high temperatures.
• Extreme mechanical long-term stability against sudden changes in pressure.
• Only the latest generation of filter media is used, with added synthetic fibers, impregnation and high filtration grades with a large dirt-holding capacity.
• High-quality seals and gaskets as well as a secure and reliable connection between the seal, end cap and filter paper.

High-quality Hengst oil filters guarantee a supply of clean oil under all operating conditions, thereby creating the basic conditions for optimum engine performance and operational reliability with longer and longer service intervals.

Hengst Fuel Filter

Hengst fuel filters remove particles of rust and dust, tank residues, water and other substances that can adversely affect the operation of modern fuel injection systems. Automakers specify filters in OE quality using state-or-the-art filter material such as Meltblown-Media.

MeltBlown-Media
Meltblown media is manufactured on the basis of polyester and therefore guarantee a significantly longer service life than cellulose media. Compared to single-ply cellulose medium, the Meltblown medium has several plies with a gradient structure. A special melt-blow process creates very fine fibers that make possible a very large pore volume in the finished filter media. The filter media is optimally adapted to the requirements of the vehicle manufacturer.

• OE-Equivalent and direct fit application.
• OE quality mounting brackets, connectors and fittings.
• State-or-the-art high efficient MeltBlown filter media
• Provides protection against fuel system wear and corrosion

Hengst fuel filters are precisely coordinated with the modern and highly sensitive fuel injection systems and also have pressure regulators and thermostat valves when required.

Warranty Information: 12 month - 12,000 mile limited warranty against defects in material and workmanship.

Hengst Diesel Fuel Filter

Hengst fuel filters remove particles of rust and dust, tank residues, water and other substances that can adversely affect the operation of modern fuel injection systems. Automakers specify filters in OE quality using state-or-the-art filter material such as Meltblown-Media.

MeltBlown-Media
Meltblown media is manufactured on the basis of polyester and therefore guarantee a significantly longer service life than cellulose media. Compared to single-ply cellulose medium, the Meltblown medium has several plies with a gradient structure. A special ?melt-blow? process creates very fine fibers that make possible a very large pore volume in the finished filter media. The filter media is optimally adapted to the requirements of the vehicle manufacturer.

• OE-Equivalent and direct fit application.
• OE quality mounting brackets, connectors and fittings.
• State-or-the-art high efficient MeltBlown filter media
• Provides protection against fuel system wear and corrosion

Variants of this filter are, on one hand, a high-pressure screw-on fuel filter for modern diesel engines with very demanding requirements and a screw-on fuel filter with a water reservoir. In this variant, an electronic conductivity sensor indicates accumulated water which can be eliminated by means of a drain plug.

Warranty Information: 12 month - 12,000 mile limited warranty against defects in material and workmanship.

Hengst Activated Charcoal Cabin Filter

Hengst activated charcoal cabin filters are manufactured to the specifications of leading automakers and are manufactured with a laminated construction consisting of particle filter fabric, activated carbon layer and substrate medium can absorb both particles like the pollen filter as well as odors and harmful gases.

• OE Equivalent and a Direct Fit Application.
• Activated charcoal layer absorbs toxic and foul-smelling gases.
• The Carbon Activated filter will noticeably reduce and even eliminate hydrocarbon molecules, benzene, odors and other gases.
• Removes spores, pollen, particulates, bacteria, fungi and road dust.
• Larger particles (> 3µm) are mechanically separated from the airflow by the dense weave of the filter fabric.
• Manufactured to the specifications of leading automakers as well as the strictest standards in terms of health, safety and driving comfort.

Activated Charcoal Cabin Air Filters: Cabin air filters with activated carbon elements remove harmful exhaust fumes, dirt and dust as well as high ozone concentrations and unpleasant smells. Their pleat bellows consist of three layers: an activated carbon layer is sandwiched between two layers of non-woven materials. The filter layers are heat-fused, which means that glues or solvents are not used at all. Depending on the vehicle type, activated carbon filters are also available that can be used instead of conventional cabin air filters.

Warranty Information: 12 month - 12,000 mile limited warranty against defects in material and workmanship.
