The 1K0819644 is an OE-quality cabin filter built for Audi A3 (2003-2013). It is a drop-in replacement: same outer dimensions, same sealing profile and same mounting points as the original part, so no modification is needed at service time.

Vehicle Compatibility

Year range is a fitment guide for the A3 generation that uses this part number. Always compare the number on your old filter with 1K0819644 before ordering; engines and trim levels of the same model can use different elements.

Technical Specifications

Why buyers choose this element

• Fit-first tooling — built from the original sample, so the seal seats without force.
• Stable filtration — uniform pleat spacing keeps pressure drop low across the service interval.
• Repeatable supply — produced in-house, the same specification is available on re-orders months later.
• Mixed-container friendly — can be consolidated with other filter numbers in one shipment to reduce freight per unit.
