KAX Engine & Cabin Air Filter Kit for Chevrolet GMC — CA10110/CF11663, Activated-Charcoal Cabin, OE Fit

The KAX CA10110 CF11663 kit is a two-piece replacement set containing one engine air filter and one cabin air filter designed to fit select Chevrolet, GMC, Buick and Saturn models.

This compact maintenance bundle combines vehicle-fit filters and activated-charcoal cabin media into a single purchase so you can refresh engine intake protection and in‑car air quality at the same time. The kit replaces OE-style filters for Chevrolet Traverse (2009–2017), GMC Acadia (2007–2016 and Acadia Limited 2017), Buick Enclave (2008–2017) and Saturn Outlook (2007–2010). It’s an economical way to keep both systems maintained on a regular schedule without hunting down separate parts.

How will this kit affect engine performance and fuel economy?

Replacing a clogged engine air filter restores unrestricted airflow to the engine, which helps the combustion system work efficiently. While it won’t increase horsepower dramatically, a clean filter supports consistent throttle response and can help maintain designed fuel economy under normal driving conditions.

• Engine air filter captures dust and road debris before the intake tract
• OE-compatible dimensions ensure proper fit and sealing
• Improved airflow stability preserves combustion efficiency
• Simple swap reduces risk of vacuum leaks from poor fitment

What benefits does the cabin filter provide for in‑car comfort?

The cabin filter in this KAX kit uses coconut shell-activated charcoal to help neutralize odors and trap fine particulates before they enter the passenger compartment. That means fresher smelling air and reduced dust, pollen and road particulate exposure for occupants during daily driving.

• Activated charcoal layer reduces common vehicle odors
• Multi-layer media captures pollen, dust and airborne particles
• Helps HVAC system maintain efficient airflow and defogging
• OE-style size makes replacement quick and reliable

How easy is installation and when should I replace both filters?

Both filters are designed for straightforward, tool-light replacement—most DIYers can swap them in about five minutes per filter depending on vehicle layout. KAX recommends replacing the engine and cabin filters together every 12 months or roughly every 12,000 miles to keep both intake and cabin systems performing well.

• Many installations require no special tools; consult vehicle manual
• Simultaneous replacement saves time and recurring costs
• Regular intervals prevent heavy contamination and reduced HVAC performance
• Keep old filters for diagnostics or inspection if desired

Are these filters compatible with my specific vehicle model year?

The CA10110 CF11663 kit is specifically matched to common OE dimensions and fitments for: Chevrolet Traverse (2009–2017), GMC Acadia (2007–2016 and Acadia Limited 2017), Buick Enclave (2008–2017), and Saturn Outlook (2007–2010). Always double-check part numbers against your vehicle’s engine and HVAC configuration before purchasing.

• Fits listed model years and typical stock engine/HVAC setups
• Check current owner’s manual or existing filter part numbers to confirm
• Contact seller or provide VIN for final fitment verification if unsure

Who is this for: The KAX CA10110 CF11663 kit is ideal for owners and DIY mechanics who service mid‑sized SUVs and crossover vehicles from Chevrolet, GMC, Buick or Saturn and want a single, convenient purchase to refresh both engine intake and cabin air. It suits drivers focused on routine maintenance, fleet technicians stocking common replacement parts, and anyone who prefers activated‑charcoal cabin filtration for odor control and improved passenger air quality. If you maintain your vehicle on a schedule and want an economical, OE-compatible replacement set, this kit streamlines the job and helps keep both systems performing as intended.
