Sourced from FILTRON, this air cleaner (AR 371) combines precision engineering with durable materials to meet the demands of everyday driving and extended service intervals. Technical specifications — Height [mm]: 184 mm, Outer Diameter [mm]: 152 mm, Filter type: Stainless Steel, Inner Diameter 1 [mm]: 86 mm, Inner Diameter 2 [mm]: 86 mm — are verified against the OEM data sheet to guarantee fitment accuracy and performance parity with the original equipment. Verified to fit AUDI models. All compatibility data is cross-checked against the TecDoc database — select your vehicle to confirm the part matches your specific engine and year. This part supersedes original equipment references: 0 986 AF2 833, 112 321 0005, 1678084480, 1 987 429 400 and 33 more.

All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops. If fitment or specifications do not match your vehicle, our technical team can help identify the correct alternative — use the vehicle selector or contact us with your VIN for a guaranteed-fit recommendation. Replacing worn components on schedule preserves your vehicle's safety, reliability, and resale value — and aftermarket parts from established brands deliver OEM-equivalent performance at a fraction of the dealer price.

Tools needed: none for most vehicles (airbox clips open by hand); some require a flat-head screwdriver or T20 Torx. Difficulty: Easy DIY.
