Pro DRY S replacement with the correct engine and housing

The aFe 31-10156 replaces the original airbox filter in the specified applications with oil-free synthetic media. The exact current manufacturer specifies N54:135i E82/E882008–2010,335i E90/E92/E932007–2010,535i E60/E612008–2010 and Z42009–2016. The old title implied135i/335i/535i coverage through2015, which the primary does not establish. BMW confirms the135i changed to N55 for model year2011. The old135i2008–2012 app range is limited to2008–2010 as a source-conflict hold; this is not a physical filter-installation test or a declaration that every N55 housing is incompatible. Exact dry-part retailers identify the existing2011 1 Series M and335is2011–2013 N54 rows; those retained N54 applications are distinct from ordinary later335i. The missing Z4 sDrive35i2009–2016 named row is restored with current manufacturer Z4 family bounds and exact retailer35i identity, alongside existing sDrive35is2011–2016. No new740i,335i N55 or later chassis approval is inferred from a related engine. The primary cotton-gauze overview conflicts with its dedicated non-oiled synthetic three-layer Pro DRY S section; use the dedicated media 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.
  • No numerical airflow-gain, horsepower or efficiency result is published on the exact current primary. Oiled Pro5R figures are not the test result of this dry element.

Frequently Asked Questions

What is the 31-10156?

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 N54:135i E82/E882008–2010,335i E90/E92/E932007–2010,535i E60/E612008–2010 and Z42009–2016. The old title implied135i/335i/535i coverage through2015, which the primary does not establish. BMW confirms the135i changed to N55 for model year2011. The old135i2008–2012 app range is limited to2008–2010 as a source-conflict hold; this is not a physical filter-installation test or a declaration that every N55 housing is incompatible. Exact dry-part retailers identify the existing2011 1 Series M and335is2011–2013 N54 rows; those retained N54 applications are distinct from ordinary later335i. The missing Z4 sDrive35i2009–2016 named row is restored with current manufacturer Z4 family bounds and exact retailer35i identity, alongside existing sDrive35is2011–2016. No new740i,335i N55 or later chassis approval is inferred from a related engine. The primary cotton-gauze overview conflicts with its dedicated non-oiled synthetic three-layer Pro DRY S section; use the dedicated media 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?

No numerical airflow-gain, horsepower or efficiency result is published on the exact current primary. Oiled Pro5R figures are not the test result of this dry element.

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 old135i2011–2012 scope held?

BMW identifies the135i N55 transition from model year2011, while the current exact filter primary names N54 and2008–2010. The later portion is withheld as an unresolved engine/housing source conflict, not claimed physically incompatible from a fitting test.

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

  1. Read the exact manufacturer product information for 31-10156 and the original vehicle airbox service procedure.
  2. 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.
  3. 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.
  4. Seat the polyurethane frame evenly without folding the bump seal or adding sealant. Close and secure the original housing and inspect all its attachments.
  5. 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.

31-10156: verify the original filter interface before operation.
