KAX Engine & Cabin Air Filter Kit for Subaru Outback/Legacy 2010–2019 — 2-Piece Kit with Charcoal Cabin Filter

KAX CA9997 CF10285 is a two-piece replacement kit—one engine air filter and one cabin air filter—designed to restore airflow and reduce odors in Subaru Outback and Legacy models from 2010 to 2019.

Whether you’re scheduling routine maintenance or replacing old, clogged filters, this KAX combo gives both engine and interior filtration in a single purchase. Each filter is built to match the fit and airflow requirements of Subaru Outback and Legacy vehicles covering model years 2010 through 2019. The cabin filter uses coconut shell–activated charcoal and a multi-layer media to help control odors and particles, while the engine filter focuses on preventing debris from reaching the intake system.

How will this kit affect my car’s performance?

Clean filters help the engine breathe properly and can maintain designed fuel efficiency and throttle response. Replacing a restricted engine filter removes a common cause of reduced power and higher fuel consumption, especially in older maintenance intervals.

• Engine filter restores designed airflow to the intake system.
• Less strain on the air metering sensors and fuel trim systems.
• Helps stabilize idle and transient acceleration behavior.
• Both filters are matched to Subaru Outback/Legacy specifications for fit.

Will the cabin filter reduce smells and allergens inside the car?

The cabin filter in this KAX kit includes activated charcoal made from coconut shell, which adsorbs many common odors and volatile organic compounds. Combined with multi-layer particulate filtration, it reduces visible dust and some airborne irritants that would otherwise enter the passenger compartment.

• Activated charcoal layer targets odors from traffic and exhaust.
• Particle media captures pollen, dust, and larger airborne debris.
• Improves perceived indoor air freshness during commutes.
• Recommended replacement interval helps maintain consistent performance.

How easy is installation and what should I replace at the same time?

Both filters are designed for straightforward replacement and most installations take about five minutes with basic tools or none at all. KAX packages the matched engine and cabin filters so you can service both systems in one visit, simplifying scheduled maintenance.

• One kit contains both the engine air filter and cabin air filter for Subaru Outback/Legacy 2010–2019.
• Typical install time for each filter: roughly five minutes.
• Instructions follow OEM access points and filter orientations for correct fit.
• Replacing both filters together avoids staggered wear and repeated labor.

When should I replace this KAX filter kit?

KAX recommends changing both the engine and cabin filters together every 12 months or approximately every 12,000 miles, whichever comes first. Environmental conditions like heavy dust, construction zones, or driving in pollen season may justify earlier replacement.

• Standard recommendation: every 12 months / 12,000 miles.
• Shorten interval in dusty or high-pollen environments.
• Inspect during routine oil changes to confirm condition.
• Buying the combo helps synchronize future replacements and reduce cost.

Who is this for: The KAX CA9997 CF10285 kit is built for Subaru Outback and Legacy owners (2010–2019) who want a convenient, value-minded replacement package that addresses both engine protection and in-cabin air quality. It’s ideal for DIY drivers, professional technicians doing routine service, or anyone looking to combine two common maintenance items into a single, time-saving purchase.
