Pro DRY S replacement with the correct engine and housing
The aFe 31-10247 replaces the original airbox filter in the specified applications with oil-free synthetic media. The exact current manufacturer specifies Tundra 2013–2021 4.6L/5.7L V8, Sequoia 2014–2022 5.7L V8 and Tacoma 2016–2023 3.5L V6, but expressly limits this flexible replacement to original Toyota 17801-0P100 and 17801-0S020 elements. The manufacturer directs rigid 17801-38030 and 17801-0S010 applications to a separately numbered rigid filter. Flexible versus rigid refers to the original panel interface, not the engine fuel being gasoline or flex fuel. Therefore the original named-trim and year rows remain conditional on the actual original part number and housing; they are not blanket approval for every engine or filter revision in those models. Exact retailer tables also list older Tundra 4.0L V6 scopes, but no such new engine rows are inferred here. The primary overview contains a cotton-gauze phrase while its dedicated Pro DRY S section and media option specify three oil-free synthetic layers; this inconsistency is qualified without treating the filter as an oiled cotton element.
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 manufacturer gives no numerical airflow-gain or efficiency percentage for this element. A generic retailer efficiency field or oiled option’s value is not transferred, and no horsepower gain is guaranteed.
Fitment
| Detail | Value |
|---|---|
| Tundra / Sequoia / Tacoma | Current primary engine-family bounds 2013–2021 / 2014–2022 / 2016–2023; original named bounds retained |
| Required original flexible elements | Toyota 17801-0P100 or 17801-0S020 only, per exact manufacturer note |
| Rigid original elements | Toyota 17801-38030 or 17801-0S010 are a different interface; not this flexible replacement |
| Selection condition | Inspect actual original element/housing; year, trim or flex-fuel badge alone is insufficient |
| Media publication conflict | Primary cotton-gauze phrase conflicts with dedicated synthetic Pro DRY S section; no oiling instruction inferred |

Frequently Asked Questions
What is the 31-10247?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 Tundra 2013–2021 4.6L/5.7L V8, Sequoia 2014–2022 5.7L V8 and Tacoma 2016–2023 3.5L V6, but expressly limits this flexible replacement to original Toyota 17801-0P100 and 17801-0S020 elements. The manufacturer directs rigid 17801-38030 and 17801-0S010 applications to a separately numbered rigid filter. Flexible versus rigid refers to the original panel interface, not the engine fuel being gasoline or flex fuel. Therefore the original named-trim and year rows remain conditional on the actual original part number and housing; they are not blanket approval for every engine or filter revision in those models. Exact retailer tables also list older Tundra 4.0L V6 scopes, but no such new engine rows are inferred here. The primary overview contains a cotton-gauze phrase while its dedicated Pro DRY S section and media option specify three oil-free synthetic layers; this inconsistency is qualified without treating the filter as an oiled cotton element.
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 manufacturer gives no numerical airflow-gain or efficiency percentage for this element. A generic retailer efficiency field or oiled option’s value is not transferred, and no horsepower gain is guaranteed.
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 flexible mean the filter is only for flex-fuel engines?No. It describes the original filter panel interface. Match Toyota 17801-0P100 or 17801-0S020 and the housing. A flex-fuel badge or common model year does not make a rigid original element interchangeable with this flexible replacement.
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 31-10247 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.
