Pro DRY S replacement with the correct engine and housing

The aFe 31-10238 replaces the original airbox filter in the specified applications with oil-free synthetic media. The current exact manufacturer identifies M2 Competition F87 2019–2021 and M3/M4 F80/F82/F83 2015–2020 with the S55, plus M6 F12/F13/F06 2012–2018 with the S63. It explicitly supplies two elements, not one. Exact per-part retailer tables also support the existing F10 M5 2013–2016 and M6 Gran Coupe 2014–2019 rows; those detailed scopes are retained with their source attribution rather than deleted because the short manufacturer heading omits M5 or stops at 2018 for the combined M6 family. The original individual M3 2015–2018, M4 2015–2020, CS 2019–2020, GTS 2016 and M2 Competition 2019–2021 bounds remain unchanged. The M5 retailer 2012 start differs from the carried US 2013 start, so no earlier application is added. No newer S58 M3/M4 or base N55 M2 interchange is inferred.

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 current exact manufacturer does not publish a numerical airflow gain or efficiency percentage for this pair. Pleat depth and count are not power gains, and neither a different media option nor a single-filter claim is transferred.

Frequently Asked Questions

What is the 31-10238?

Two Pro DRY S OE-replacement air-filter elements 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 identifies M2 Competition F87 2019–2021 and M3/M4 F80/F82/F83 2015–2020 with the S55, plus M6 F12/F13/F06 2012–2018 with the S63. It explicitly supplies two elements, not one. Exact per-part retailer tables also support the existing F10 M5 2013–2016 and M6 Gran Coupe 2014–2019 rows; those detailed scopes are retained with their source attribution rather than deleted because the short manufacturer heading omits M5 or stops at 2018 for the combined M6 family. The original individual M3 2015–2018, M4 2015–2020, CS 2019–2020, GTS 2016 and M2 Competition 2019–2021 bounds remain unchanged. The M5 retailer 2012 start differs from the carried US 2013 start, so no earlier application is added. No newer S58 M3/M4 or base N55 M2 interchange is inferred.

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 current exact manufacturer does not publish a numerical airflow gain or efficiency percentage for this pair. Pleat depth and count are not power gains, and neither a different media option nor a single-filter claim is transferred.

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 the package contain one or two filters?

Two elements are explicitly listed by the manufacturer. Check and service both original housings. The generic older one-component contents sentence does not override that exact two-element specification.

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 31-10238 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.

31-10238: verify the original filter interface before operation.
