Performance Air Filter for Audi 80/90/100 Quattro

Unleash the Legend: BMC High-Flow Induction for Audi 5-Cylinder & Quattro Platforms

Who It’s For: Engineered for Audi 80, 90, and Quattro owners running the legendary 5-cylinder powerplants who are tired of the stock sluggishness and restrictive intake breathing.

The Symptom: The factory intake on your classic Audi was designed for quiet commuting, not performance. It utilizes a thick, corrugated paper filter that creates significant air resistance. On the 5-cylinder platform, this restriction causes a noticeable lag in throttle response, especially when the Quattro drivetrain’s rotational inertia demands immediate torque. As the paper filter loads with dust, the pressure drop across the intake increases, forcing the engine to work harder just to breathe, which kills top-end pull and fuel efficiency.

The Engineering Fix: This BMC system replaces the restrictive OEM paper element with a high-performance, multi-layered cotton gauze media. By utilizing a "Full Moulding" production process, the filter is created from a single mould with no welded joints, ensuring a perfect seal and zero structural failure. The fluid dynamics are vastly improved; the oiled cotton allows for a higher volume of air to pass through while capturing impurities as small as 7 microns. This results in a higher oxygen density in the intake manifold, allowing your Audi to overcome drivetrain drag with much sharper throttle snap.

Why Mechanics Choose This Kit

• Enhanced Volumetric Efficiency: By reducing the intake stroke’s vacuum resistance, this filter allows more air into the cylinders, maximizing the power potential of the 5-cylinder engine.
• Superior Filtration: Unlike cheap aftermarket filters, BMC guarantees containment of impurities down to 7 microns, surpassing the OEM 10-micron standard while still increasing total CFM (Cubic Feet per Minute).
• Endless Service Life: Constructed with epoxy-coated alloy mesh to resist petrol fumes and oxidation, this filter is fully washable and regenerable, meaning it’s the last filter your Audi will ever need.
