The aFe 31-10155 replaces the original airbox filter in the specified applications with oil-free synthetic media. The exact current manufacturer specifies Jeep Wrangler JK2007–2018 V6 3.6L/3.8L. The engine alternatives follow their actual production years, not both engines in every year. The2018 model year contains both JK carryover and JL; this filter scope is JK only. Original2018 Wrangler rows are represented as the real Wrangler JK model with their existing named trims, and the missing2018 Rubicon row is restored from exact JK application detail. Earlier2007–2017 Wrangler rows and existing disjoint trim scopes remain unchanged. No JL, diesel,4xe or replacement aftermarket intake element is inferred. The primary overview says oiled, but its dedicated Pro DRY S section explicitly specifies three-layer non-oiled synthetic media. A retailer oiled-cotton Restore Kit/oil package conflicts with that dry identity and does not establish included service supplies.
| Detail | Value |
|---|---|
| Manufacturer application | Wrangler JK2007–2018 V6 3.6L/3.8L, with actual production-engine and original-housing limits |
| 2018 generation | Wrangler JK carryover; not Wrangler JL despite the shared model year |
| 2018 named row | Rubicon restored; other original2018 trim rows retained on actual Wrangler JK model |
| Media identity | Three-layer oil-free synthetic Pro DRY S; oiled overview wording is conflicting |
| Package boundary | One replacement panel; no documented cleaner, Restore Kit or oil bottle included |

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 Jeep Wrangler JK2007–2018 V6 3.6L/3.8L. The engine alternatives follow their actual production years, not both engines in every year. The2018 model year contains both JK carryover and JL; this filter scope is JK only. Original2018 Wrangler rows are represented as the real Wrangler JK model with their existing named trims, and the missing2018 Rubicon row is restored from exact JK application detail. Earlier2007–2017 Wrangler rows and existing disjoint trim scopes remain unchanged. No JL, diesel,4xe or replacement aftermarket intake element is inferred. The primary overview says oiled, but its dedicated Pro DRY S section explicitly specifies three-layer non-oiled synthetic media. A retailer oiled-cotton Restore Kit/oil package conflicts with that dry identity and does not establish included service supplies.
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, horsepower or filtration-efficiency result. A retailer promise or another media option’s figure is not an exact current test.
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.
Does2018 Wrangler coverage include the JL?No. The manufacturer specifies JK. Verify the actual carryover JK platform and original airbox rather than choosing by model year alone; no JL,4xe or diesel housing approval follows this application.
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.
