Pro DRY S replacement with the correct engine and housing
The aFe 31-10205 replaces the original airbox filter in the specified applications with oil-free synthetic media. The exact current manufacturer specifies 135i E82/E88 and 335i E90/E92/E93 2011–2013 with the N55 3.0L turbo engine. Exact ECS engine entries also identify N55 335xi and E84 X1 xDrive35i; the carried X1 2013–2015 and 135is 2013 rows have exact retailer year support. The older title’s X1 2011 start is not retained as fitment evidence. One exact retailer also lists the original 2011 335is, but BMW’s own technical release explicitly identifies that model as N54 twin-turbo rather than N55. That legacy row and its native selection are withheld as a source-conflict hold pending exact original-filter/housing proof, not a physical test or a declaration that every N54 filter is incompatible. No new later F30 335i, S55, B58 or shared-displacement application is inferred. Current primary cotton-gauze overview wording conflicts with its dedicated non-oiled synthetic Pro DRY S paragraph; dry synthetic maintenance governs.
Key Features
- Oil-free synthetic filtration media.
- Washable oil-free synthetic media. Use the specified aFe POWER CLEANER, rinse appropriately and dry fully; do not apply air-filter oil. The current exact manufacturer specifies three layers of oil-free synthetic media.
- Rounded open pleats provide usable filter area and dust-holding capacity.
- Full polyurethane perimeter frame and progressive bump seal.
- No numerical flow-gain, filtration-efficiency or horsepower result is published on the current exact manufacturer page for this element. Do not substitute another BMW media option or complete-intake test.

Frequently Asked Questions
What is the 31-10205?One Pro DRY S 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 exact current manufacturer specifies 135i E82/E88 and 335i E90/E92/E93 2011–2013 with the N55 3.0L turbo engine. Exact ECS engine entries also identify N55 335xi and E84 X1 xDrive35i; the carried X1 2013–2015 and 135is 2013 rows have exact retailer year support. The older title’s X1 2011 start is not retained as fitment evidence. One exact retailer also lists the original 2011 335is, but BMW’s own technical release explicitly identifies that model as N54 twin-turbo rather than N55. That legacy row and its native selection are withheld as a source-conflict hold pending exact original-filter/housing proof, not a physical test or a declaration that every N54 filter is incompatible. No new later F30 335i, S55, B58 or shared-displacement application is inferred. Current primary cotton-gauze overview wording conflicts with its dedicated non-oiled synthetic Pro DRY S paragraph; dry synthetic maintenance governs.
Is the Pro DRY S media oiled?Washable oil-free synthetic media. Use the specified aFe POWER CLEANER, rinse appropriately and dry fully; do not apply air-filter oil. The current exact manufacturer specifies three layers of oil-free synthetic media.
Does the flow percentage guarantee more engine power?No numerical flow-gain, filtration-efficiency or horsepower result is published on the current exact manufacturer page for this element. Do not substitute another BMW media option or complete-intake test.
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.
Why is the original 2011 335is row withheld?BMW identifies that model as N54 while the exact manufacturer filter scope and ECS engine table specify N55. An exact retailer positive row does not resolve the original-housing conflict. The hold is not a physical incompatibility test or a blanket statement about all N54 applications.
When should I clean it?Inspect according to actual dust exposure and restriction. Washable oil-free synthetic media. Use the specified aFe POWER CLEANER, rinse appropriately and dry fully; do not apply air-filter oil. The current exact manufacturer specifies three layers of oil-free synthetic media. Use low-pressure rinse from the clean side toward the dirty side, let the element dry naturally before reinstalling. Do not use heat, compressed air or any filter 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 31-10205 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 oil-free synthetic media. Use the specified aFe POWER CLEANER, rinse appropriately and dry fully; do not apply air-filter oil. The current exact manufacturer specifies three layers of oil-free synthetic 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 oil-free Pro DRY S maintenance directions. Read the manufacturer media maintenance guidance.
