The aFe 31-10278 replaces the original airbox filter in the specified applications with oil-free synthetic media. The exact current manufacturer specifies Volkswagen Atlas 2018β2025 with the 2.0L turbo four-cylinder or 3.6L V6 and three oil-free synthetic layers. Its 25 mm figure is rounded pleat depth, not overall filter height. Exact per-part retailer tables and an independent AutoZone listing also support Atlas Cross Sport applications; they are separate evidence beyond the current Atlas headline. Five named Cross Sport 2020β2021 groups are restored from the exact table, and Atlas SE/SEL bounds are extended through 2024 where the exact table identifies the later 2.0L engine. Earlier 3.6L availability must not be carried into every later trim or year. Other original Atlas scopes remain unchanged. Additional regional Comfortline/Execline/Trendline rows, R-Line variants and 2025 named-trim bounds are not inferred from the broad model header.

Which application should I verify?The exact current manufacturer specifies Volkswagen Atlas 2018β2025 with the 2.0L turbo four-cylinder or 3.6L V6 and three oil-free synthetic layers. Its 25 mm figure is rounded pleat depth, not overall filter height. Exact per-part retailer tables and an independent AutoZone listing also support Atlas Cross Sport applications; they are separate evidence beyond the current Atlas headline. Five named Cross Sport 2020β2021 groups are restored from the exact table, and Atlas SE/SEL bounds are extended through 2024 where the exact table identifies the later 2.0L engine. Earlier 3.6L availability must not be carried into every later trim or year. Other original Atlas scopes remain unchanged. Additional regional Comfortline/Execline/Trendline rows, R-Line variants and 2025 named-trim bounds are not inferred from the broad model header.
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 page publishes no numerical flow-gain or filtration-efficiency percentage. The oiled option and catalog fields for another filter are 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 the 2025 Atlas headline extend every trim through 2025?No. Model-family scope and exact named-trim evidence are separate. The later table identifies 2.0L engines for specific rows. Retained earlier 3.6L rows and the restored Cross Sport groups still require the correct original housing; regional trim names are not invented.
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.
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.
