Pro DRY S replacement with the correct engine and housing
The aFe 31-10123 replaces the original airbox filter in the specified applications with oil-free synthetic media. The current exact manufacturer specifies Toyota Tacoma2005–2023 2.7L four-cylinder. Exact per-part retailer engine detail identifies Tacoma2005–2015 original unnamed/Pre Runner2.7L and2016–2022 SR/SR5 2.7L, restoring the missing2021–2022 years in both SR and SR5 rows. The primary2023 family endpoint is documented without inventing named2023 trims. The original2010 4Runner SR5 row is separately corroborated by an exact dry-part retailer as2.7L, not a blanket4.0L or all-4Runner application. A trim badge can be shared with a V6, so verify the actual2.7L engine and original airbox. No later turbocharged Tacoma, aftermarket intake or V6 filter interchange is inferred. The exact current manufacturer specifies three oil-free synthetic layers and street/light off-road use; no generic two-layer retailer wording overrides that exact 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 current exact manufacturer publishes no numerical airflow-gain, horsepower or efficiency result. A different Toyota panel or another media option’s test is not substituted.

Frequently Asked Questions
What is the 31-10123?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 Toyota Tacoma2005–2023 2.7L four-cylinder.

The exact current manufacturer specifies three oil-free synthetic layers and street/light off-road use; no generic two-layer retailer wording overrides that exact 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 current exact manufacturer publishes no numerical airflow-gain, horsepower or efficiency result. A different Toyota panel or another media option’s test is not 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.
Does every SR5 or Pre Runner use this filter?No. The trim name alone does not establish the engine or airbox. This manufacturer scope is2.7L four-cylinder; confirm the actual original element and retain the individual year bounds, including the separately qualified2010 4Runner row.
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
