The aFe 31-10273-MA replaces the original airbox filter in the specified applications with oil-free synthetic media. The exact current manufacturer identifies two three-layer oil-free synthetic elements for Q50 3.5L 2014–2018 and 3.7L 2014–2015. The original 2019 title endpoint was not an all-engine application. Exact MVP per-part engine detail separately confirms the 3.5L hybrid, including Hybrid 2015–2018 and Hybrid Luxe 2018; those two missing named groups are restored without replacing the already correct Hybrid Premium 2014–2017 and Hybrid Sport 2014–2015 bounds. The manufacturer headline prints V35 beside 3.5L while the exact engine-specific retailer identifies V37; that chassis-label conflict is not copied as proof of an older G35 housing. A 3.0L turbo Q50/Q60 or a van sharing a generic retailer table is not approved from this pair’s model name. The package contains two elements, not two complete intake systems.

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 identifies two three-layer oil-free synthetic elements for Q50 3.5L 2014–2018 and 3.7L 2014–2015. The original 2019 title endpoint was not an all-engine application. Exact MVP per-part engine detail separately confirms the 3.5L hybrid, including Hybrid 2015–2018 and Hybrid Luxe 2018; those two missing named groups are restored without replacing the already correct Hybrid Premium 2014–2017 and Hybrid Sport 2014–2015 bounds. The manufacturer headline prints V35 beside 3.5L while the exact engine-specific retailer identifies V37; that chassis-label conflict is not copied as proof of an older G35 housing. A 3.0L turbo Q50/Q60 or a van sharing a generic retailer table is not approved from this pair’s model name. The package contains two elements, not two complete intake systems.
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 publishes no numerical airflow gain or efficiency percentage for this pair. A percentage from a separate Q60 pair, oiled filter or general Pro DRY S description is not 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 this approve the 3.0L turbo Q50 or Q60?No. This exact primary specifies the 3.5L and 3.7L engine scopes stated above. Another filter pair has its own part number and application; neither a general Infiniti model name nor a retailer’s mixed table certifies interchange.
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.
