The aFe 31-10242 replaces the original airbox filter in the specified applications with oil-free synthetic media. The exact current manufacturer specifies Porsche 911 991 2012–2016 3.4L/3.8L and explicitly includes two oil-free synthetic elements. Exact per-part retailer tables independently list the retained broader GT3, GT3 RS, R, Speedster and Turbo scopes; later 4.0L performance variants and 2012 transition-year cars are not manufacturer-certified solely by the current 991 headline. Some 2012 carryover variants and the R model year differ among those sources, so their original bounded rows remain chassis/engine/housing source holds. The missing Carrera Black Edition 2016 and Targa 4 2014–2016 named rows are restored from exact per-part retailer tables within the manufacturer 991 family. The manufacturer’s linked Instructions PDF was actually opened and visually read: it is a Dodge Cummins charge-air manifold instruction sheet for another part. It is not installation guidance for this Porsche filter pair. No manifold hardware, torque, threadlocker or emissions sticker instruction is transferred. Separate GT3/GT3 RS native collection mapping remains held pending clearer exact model-generation proof; the existing 911 placement is retained.
| Detail | Value |
|---|---|
| Porsche 911 991 | Current primary 2012–2016 3.4L/3.8L; verify actual chassis in transition years |
| Carrera Black Edition / Targa 4 | 2016 / 2014–2016 missing named retailer groups restored |
| GT3 / GT3 RS / R / Speedster / Turbo | Original bounded retailer rows retained with engine, generation and year-conflict qualifications; no blanket extension |
| Quantity | Two Pro DRY S elements in this package; not one element or two complete pairs |
| Manufacturer-linked PDF | Wrong Dodge manifold document, visually verified; no Porsche procedure or numeric airbox torque certified from it |
31-10242: verify the exact engine, original element and housing. Model or trim names alone do not establish all-engine interchangeability.

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 exact current manufacturer specifies Porsche 911 991 2012–2016 3.4L/3.8L and explicitly includes two oil-free synthetic elements. Exact per-part retailer tables independently list the retained broader GT3, GT3 RS, R, Speedster and Turbo scopes; later 4.0L performance variants and 2012 transition-year cars are not manufacturer-certified solely by the current 991 headline. Some 2012 carryover variants and the R model year differ among those sources, so their original bounded rows remain chassis/engine/housing source holds. The missing Carrera Black Edition 2016 and Targa 4 2014–2016 named rows are restored from exact per-part retailer tables within the manufacturer 991 family. The manufacturer’s linked Instructions PDF was actually opened and visually read: it is a Dodge Cummins charge-air manifold instruction sheet for another part. It is not installation guidance for this Porsche filter pair. No manifold hardware, torque, threadlocker or emissions sticker instruction is transferred. Separate GT3/GT3 RS native collection mapping remains held pending clearer exact model-generation proof; the existing 911 placement is retained.
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 or filtration-efficiency percentage is published on the current exact manufacturer page for this pair. Neither a generic Pro DRY S figure nor another Porsche filter’s performance claim is substituted.
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.
Should I follow the PDF linked as Instructions?No. The actual linked file contains instructions for an unrelated Dodge Cummins charge-air manifold. Follow the correct Porsche original-housing service procedure and oil-free filter maintenance guidance; no torque, threadlocker, supplied hardware or emissions sticker is borrowed from that incorrect document.
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.
The linked Instructions PDF is an unrelated Dodge manifold sheet, not a verified Porsche procedure. No numeric Porsche airbox torque is certified from it. Follow the original Porsche housing service procedure and oil-free maintenance directions. Read the manufacturer media maintenance guidance.
