The aFe 30-10181 replaces the original airbox filter in the specified applications with five layers of factory-pre-oiled cotton gauze. The current manufacturer groups Audi A4 2009–2019 and Q5 2011–2018 under a 2.0L turbo headline. Those combined ranges do not certify every A4 generation or Q5 engine; no later B9 A4 or second-generation Q5 named-trim extension is made from the headline alone. The existing individual A4 / A4 Quattro / A5 / A5 Quattro / allroad and Q5 named rows retain their separately bounded years. Exact retailer tables also identify 2013 Q7 gasoline and TDI rows outside the current 2.0L manufacturer headline. Those existing Q7 rows remain an explicit engine/housing source qualification rather than manufacturer-certified all-engine Q7 compatibility. The existing Q5 Hybrid Prestige scope is an engine-airbox application, not a universal hybrid or electric-vehicle filter. Older Cabriolet and other engine variants require their exact original element; matching only the A4 badge is insufficient. Additional named trims seen only in indexed retailer tables remain pending exact current engine/housing confirmation.
| Detail | Value |
|---|---|
| Audi manufacturer family | A4 2009–2019 / Q5 2011–2018 2.0L turbo headline; not every generation or engine |
| A4 / A4 Quattro / A5 / allroad | Existing individual body / trim / year scopes retained; exact original housing required |
| Q5 Hybrid Prestige | Existing 2013–2016 named scope retains engine/housing qualification |
| Audi Q7 source qualification | Existing 2013 retailer rows retained but broader gasoline/TDI engine proof is not certified by the current 2.0L manufacturer headline |
| Later generations | No later B9 A4 or second-generation Q5 expansion inferred from the combined headline |
30-10181: verify the exact engine, original element and housing. Model or trim names alone do not establish all-engine interchangeability.

| Pleat description | Rounded open pleats; no unverified overall dimensions |

| Flow statement | The manufacturer advertises up to 25% greater filter flow than stock. That does not mean a 25% horsepower or torque gain. |

One Pro 5R OE-replacement air-filter element for the verified housing and engine application described here; this is not a complete intake system.
Which application should I verify?The current manufacturer groups Audi A4 2009–2019 and Q5 2011–2018 under a 2.0L turbo headline. Those combined ranges do not certify every A4 generation or Q5 engine; no later B9 A4 or second-generation Q5 named-trim extension is made from the headline alone. The existing individual A4 / A4 Quattro / A5 / A5 Quattro / allroad and Q5 named rows retain their separately bounded years. Exact retailer tables also identify 2013 Q7 gasoline and TDI rows outside the current 2.0L manufacturer headline. Those existing Q7 rows remain an explicit engine/housing source qualification rather than manufacturer-certified all-engine Q7 compatibility. The existing Q5 Hybrid Prestige scope is an engine-airbox application, not a universal hybrid or electric-vehicle filter. Older Cabriolet and other engine variants require their exact original element; matching only the A4 badge is insufficient. Additional named trims seen only in indexed retailer tables remain pending exact current engine/housing confirmation.
Is the Pro 5R media oiled?Washable and reusable oiled cotton media. Use aFe POWER CLEANER and the specified blue air-filter oil; this is not oil-free Pro DRY S media.
Does the flow percentage guarantee more engine power?The manufacturer advertises up to 25% greater filter flow than stock. That does not mean a 25% horsepower or torque gain.
How does this filter seal?Its progressive bump seal and full polyurethane perimeter frame conform to the original housing. The manufacturer says separate filter gaskets or sealants are not required; the existing housing must still close and secure correctly.
Are a hose coupler and cleaning kit supplied?The exact listing identifies an OE-replacement filter. A generic Coupler Included field does not establish a separate hose package; no airbox, tube, sensor, cleaner or oil bottle is documented as supplied.
Does the broad headline certify every 2019 A4 or 2018 Q5?No. It combines model families and does not resolve generation, engine or original filter housing. Existing named rows remain bounded; later-generation applications need exact original-element and engine support before search coverage is extended.
When should I clean and re-oil it?Inspect according to actual dust exposure and restriction. Washable and reusable oiled cotton media. Use aFe POWER CLEANER and the specified blue air-filter oil; this is not oil-free Pro DRY S media. Use low-pressure rinse from the clean side toward the dirty side, let the element dry naturally and allow the specified oil to wick before reinstalling. Do not use heat, compressed air or excess oil. Do not treat an older general-care mileage example as a guaranteed interval for every vehicle or environment.
No vehicle-specific installation PDF or numeric airbox torque is linked on this exact manufacturer page. Follow the original housing service procedure and the correct oiled Pro 5R maintenance directions. Read the manufacturer media maintenance guidance.
