The aFe 31-10307 replaces the original airbox filter in the specified applications with oil-free synthetic media. The current exact manufacturer names Ford Fiesta 2014β2019 1.6L turbo and specifies three layers of oil-free synthetic media. Exact dry-part retailer tables independently identify the existing S, SE and Titanium rows alongside ST; those broader original-housing applications are not inferred from the turbo engine or deleted solely because the primary headline says turbo. Individual engine and airbox conditions still govern. The existing S/SE/ST 2014β2019 and Titanium 2014β2018 bounds are retained. A retailer also names ST Line 2019, but that additional application is recorded without adding a new row before its engine/housing detail is reconciled. The linked Instructions PDF is an older generic two-layer Pro DRY S intake-filter cleaning sheet, not a Fiesta-specific fitting manual or inspected three-layer panel revision. Its old airflow-restoration percentages and 2006 warranty page are not new guarantees for this element.

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 names Ford Fiesta 2014β2019 1.6L turbo and specifies three layers of oil-free synthetic media. Exact dry-part retailer tables independently identify the existing S, SE and Titanium rows alongside ST; those broader original-housing applications are not inferred from the turbo engine or deleted solely because the primary headline says turbo. Individual engine and airbox conditions still govern. The existing S/SE/ST 2014β2019 and Titanium 2014β2018 bounds are retained. A retailer also names ST Line 2019, but that additional application is recorded without adding a new row before its engine/housing detail is reconciled. The linked Instructions PDF is an older generic two-layer Pro DRY S intake-filter cleaning sheet, not a Fiesta-specific fitting manual or inspected three-layer panel revision. Its old airflow-restoration percentages and 2006 warranty page are not new guarantees for this 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 primary specifies three synthetic layers; the older linked care sheet two-layer wording is historical generic guidance.
Does the flow percentage guarantee more engine power?The current exact manufacturer gives no numerical flow-gain or efficiency percentage. Retailer engine torque claims, oiled-option gains and older generic care-sheet restoration percentages are not adopted.
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 turbo headline certify every S, SE or Titanium engine?No. Those existing named applications have separate exact-part retailer evidence and retain original engine/housing checks. The shared Fiesta name is not approval of every engine, intake system or later model year.
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 primary specifies three synthetic layers; the older linked care sheet two-layer wording is historical generic guidance. 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 older generic oil-free filter-care sheet with a two-layer intake illustration and 2006 warranty page. It does not supply vehicle-specific fitting, torque, included hardware or an inspected current three-layer revision. Clean appropriately, rinse and dry fully; never apply filter oil. Read the manufacturer media maintenance guidance.
