Pro 5R replacement with the correct engine and housing
The aFe 30-10205 replaces the original airbox filter in the specified applications with five layers of factory-pre-oiled cotton gauze. The current manufacturer names 2011–2013 BMW 135i E82/E88 and 335i E90/E92/E93 with the N55 3.0L turbo engine. The exact ECS engine table independently lists N55 335xi and E84 X1 xDrive35i; exact retailer year rows support the existing X1 2013–2015 and 135is 2013 scopes. The older title showing X1 from 2011 is not used as evidence for those earlier years. BMW explicitly identifies the 2011 335is as N54 twin-turbo, distinct from the N55 335i. Its legacy 2011 335is application is withheld as a source-conflict hold pending exact filter/housing proof, not a physical installation test or a claim that every N54 filter is incompatible. A broad retailer vehicle widget listing unrelated engines is not an exact fitment table. An ECS X5 N55 entry without an exact year-and-trim table is recorded but is not converted into new search rows.
Key Features
- Five layers of progressively finer oiled cotton gauze.
- 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.
- Rounded open pleats provide usable filter area and dust-holding capacity.
- Full polyurethane perimeter frame and progressive bump seal.
- The exact manufacturer overview reports 33% greater filter flow than stock. This is not a 33% horsepower or torque guarantee.

Frequently Asked Questions
What is the 30-10205?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 names 2011–2013 BMW 135i E82/E88 and 335i E90/E92/E93 with the N55 3.0L turbo engine. The exact ECS engine table independently lists N55 335xi and E84 X1 xDrive35i; exact retailer year rows support the existing X1 2013–2015 and 135is 2013 scopes. The older title showing X1 from 2011 is not used as evidence for those earlier years. BMW explicitly identifies the 2011 335is as N54 twin-turbo, distinct from the N55 335i. Its legacy 2011 335is application is withheld as a source-conflict hold pending exact filter/housing proof, not a physical installation test or a claim that every N54 filter is incompatible. A broad retailer vehicle widget listing unrelated engines is not an exact fitment table. An ECS X5 N55 entry without an exact year-and-trim table is recorded but is not converted into new search rows.
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 exact manufacturer overview reports 33% greater filter flow than stock. This is not a 33% horsepower or torque guarantee.
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 335is mean the same N55 application as 335i?No. BMW identifies the 2011 335is as an N54 twin-turbo application. The current filter manufacturer specifies N55. The older 335is row is withheld until exact filter and original housing support is available; its similarity in model name is insufficient.
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.
Installation Instructions
- Read the exact manufacturer product information for 30-10205 and the original vehicle airbox service procedure.
- With the engine off and cool, compare the new filter and original element, including the sealing interface. Resolve an engine or housing mismatch before installation.
- Open the original housing according to its service procedure, remove the old element and keep debris out of the clean intake path. Clean the housing seat.
- Seat the polyurethane frame evenly without folding the bump seal or adding sealant. Close and secure the original housing and inspect all its attachments.
- 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.
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.
