WHEELZEN Engine & Cabin Air Filter Kit for Toyota 4Runner FJ Cruiser 4.0L V6 — OEM Fit, Activated Carbon Cabin Filter

If your 4Runner or FJ Cruiser is due for routine maintenance, this matched engine and cabin filter kit from WHEELZEN gives you both under-hood filtration and in-cabin air freshness in one package. The set is engineered to fit the specified years and engines precisely, making swaps quick and straightforward without modifications. Included part numbers and cross-references help confirm compatibility before you buy.

How will this filter set affect engine performance?

Replacing a clogged engine air filter helps your V6 maintain healthy air intake flow and efficient combustion. While a new filter won't add horsepower on its own, it supports steady performance and can help preserve fuel economy over time.

• Direct replacement for OEM part 17801-0P010 and equivalents
• High-efficiency media captures dust, dirt, and debris
• Designed to maintain proper airflow to the intake system

What does the cabin filter do for my vehicle's interior?

The cabin filter in this kit uses activated carbon to reduce odors and trap airborne particles before they enter the passenger compartment. It improves interior air quality and protects HVAC components from dust buildup.

• Activated carbon layer helps reduce smells and gases
• Traps pollen, road dust, and particulate contaminants
• Prevents debris from accumulating in the blower and vents
