Pro DRY S replacement with the correct engine and housing
The aFe 31-10131 replaces the original airbox filter in the specified applications with oil-free synthetic media. The current exact manufacturer specifies BMW128i/325i/328i/330i E82/E88/E90/E91/E92/E932006–2013 3.0L N52/N53. Retain the original individual128i/325i/325xi/328i/328i xDrive/328xi/330i/330xi year bounds and verify actual engine, body and original airbox; a combined family endpoint does not certify every2012–2013 sedan generation. The legacy2006 330Ci entry is an E46 M54 application in primary filter-manufacturer engine catalog evidence, while2009–2010 335i is N54 in BMW-authored model ordering guides. These do not establish the specified N52/N53 application. Both legacy rows are withheld as engine/chassis source conflicts; this is not a physical fitting test or a blanket claim of incompatibility for every modified housing. A retailer header containing330ci beside E9x/N52/N53 does not resolve the actual E46 engine discrepancy. No N51, later F-series, turbo or related-engine row is newly inferred. The primary cotton-gauze overview conflicts with its dedicated non-oiled synthetic three-layer Pro DRY S paragraph; follow the dedicated dry-media maintenance specification.
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.
- The exact current primary gives qualitative airflow and dust-capacity statements without a numerical gain, horsepower or efficiency test. Another BMW filter’s99.2-percent statement is not borrowed.

Frequently Asked Questions
What is the 31-10131?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 current exact manufacturer specifies BMW128i/325i/328i/330i E82/E88/E90/E91/E92/E932006–2013 3.0L N52/N53.

The legacy2006 330Ci entry is an E46 M54 application in primary filter-manufacturer engine catalog evidence, while2009–2010 335i is N54 in BMW-authored model ordering guides. These do not establish the specified N52/N53 application. Both legacy rows are withheld as engine/chassis source conflicts; this is not a physical fitting test or a blanket claim of incompatibility for every modified housing. A retailer header containing330ci beside E9x/N52/N53 does not resolve the actual E46 engine discrepancy. No N51, later F-series, turbo or related-engine row is newly inferred. The primary cotton-gauze overview conflicts with its dedicated non-oiled synthetic three-layer Pro DRY S paragraph; follow the dedicated dry-media maintenance specification.
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?The exact current primary gives qualitative airflow and dust-capacity statements without a numerical gain, horsepower or efficiency test. Another BMW filter’s99.2-percent statement is not borrowed.
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.
Are the withheld330Ci and335i rows proven physically incompatible?No physical installation test was performed. Their actual M54/N54 engine and chassis identity conflicts with the exact N52/N53 manufacturer scope. The rows are withheld pending exact housing proof, while the correctly scoped original applications remain.
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 31-10131 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.
