aFe 11-10121 is the Pro DRY S oil-free synthetic replacement element for its specified factory air-filter housing. It is an air filter, not a complete intake or new airbox.
The current page names Audi A4/A5 2009-2012 3.2L and S5 2010-2018 3.0L. Its January 2012 illustrated manual additionally names specific earlier A4/A5/Q5/S4/S5 engine and year combinations, including 4.2L S5. Exact-part retailer tables also list later S5/Sportback, allroad and TDI rows. Those broader entries do not by themselves confirm this older bolt-mounted filter interface for a later-generation housing. Confirm body generation, engine and the actual original airbox, including the two mounting studs/nuts and sensor-housing connection, before ordering.

One aFe 11-10121 replacement air-filter element, two #8 star washers and two hex-tooth nuts per the exact manual. The generic website field “Coupler Included: Yes” does not itemize a separate hose, coupling or clamp; no such extra component is certified as supplied.
aFe Power develops application-specific intake, filtration, exhaust, cooling, tuning, suspension, drivetrain, and truck-performance components supported by product testing and documented installation requirements.
Exact illustrated installation instructions
One filter, two #8 star washers and two hex-tooth nuts. These are mounting hardware, not a new mass-airflow sensor.
Is the original filter gasket reused?No. The exact manual states that the original gasket is not used with the replacement.
Which drivers does the procedure use?T20 for seven airbox screws, T10 to remove the original filter and a 9/32-inch socket for the supplied hardware. T10 appears in the steps although omitted from the short tool list.
Does seal lubrication mean oiling the filter media?No. The manual calls for a small amount of lubricant inside the flange seal to seat the original sensor housing. The three-layer synthetic media remains oil-free.
Does a later S5 retailer row prove the correct housing?No. The exact mounting interface and body generation must match. Later retailer rows are broader than the old illustrated sheet and are not blanket approval for every airbox.
What is included?One replacement air-filter element, two #8 star washers and two hex-tooth nuts per the exact manual. The generic coupler field does not itemize additional hoses or clamps; a cleaning kit and replacement housing are not listed as supplied.
How should the oil-free synthetic media be serviced?Follow current aFe Pro DRY S cleaning guidance. Use the specified cleaner and do not add oil; this part is synthetic dry media.
Does this OE filter require a CARB EO number?The current exact manufacturer page says it does not require a CARB EO number. That statement concerns this replacement filter and does not establish approval for an entire modified intake or another component.
Verify aFe 11-10121. Allow the vehicle to cool; the manufacturer recommends professional installation and eye/hand protection. Follow the exact January 2012 sheet: release the two metal mass-airflow housing retainers; remove seven T20 screws (two near the sensor plus five on top), then lift the airbox top out. A T10 driver is used to remove the old element although omitted from the short tool list. The old gasket is not reused. Install the new filter with the supplied hardware using a 9/32-inch socket; do not overtighten. Refit the upper box and seven screws. Apply a small amount of the specified lubricating substance inside the polyurethane flange seal, gently seat the original sensor housing and lock both metal retainers. This seal lubrication is separate from media maintenance: do not oil the dry media. No numeric torque or new sensor is specified.
California Proposition 65 warning: this product can expose you to chemicals known to the State of California to cause cancer and reproductive harm.
Manufacturer filter-flow and media-efficiency claims do not guarantee vehicle power gains. Actual engine, original housing and sealing interfaces must match.
