KAX Engine & Cabin Air Filter Kit for Dodge & Chrysler 2011–2023 — Direct-Fit, Charcoal Cabin

This kit pairs a high-efficiency engine air filter with a charcoal-enhanced cabin filter so you can address both engine protection and in‑car air quality in a single purchase. Each element is engineered for straightforward installation and is sized to match factory specifications for 3.6L, 6.4L, and 5.7L engines where listed. The cabin filter uses activated coconut-shell charcoal to reduce odors while the engine filter helps keep particulates out of the intake, supporting consistent engine breathing and performance.

What vehicles and engines does this KAX kit fit?

This set is manufactured to fit Dodge Charger and Challenger models from 2011–2023 and Chrysler 300 models from 2011–2023 with the listed 3.6L, 6.4L, or 5.7L engines. It matches common original-equipment dimensions for those applications to ensure a proper seal and fit.

• Fits Dodge Charger (2011–2023) — applicable engine sizes cited above
• Fits Dodge Challenger (2011–2023) — compatible with 3.6L/6.4L/5.7L
• Fits Chrysler 300 (2011–2023) — direct-fit replacement
• Sold as a two-piece kit to cover both engine intake and cabin filtration needs

How do these filters improve everyday driving and maintenance?

Replacing both filters at the same time reduces the chance of overlooking one element during routine service and helps maintain predictable cabin comfort and engine airflow. The engine filter traps dust and debris that could accelerate wear, while the charcoal cabin filter helps reduce odors and gaseous contaminants inside the vehicle.

• Dual replacement avoids staggered maintenance and potential performance dips
• Engine filter supports consistent air intake and protects internal components
• Charcoal layer in cabin filter neutralizes common vehicle odors
• Simplifies parts ordering—one SKU covers both filters

How easy is installation and what are the service intervals?

Both filters are designed for user-friendly installation and typically take about five minutes each for someone with basic tools and familiarity. KAX recommends replacing the kit together approximately every 12 months or every 12,000 miles, depending on driving conditions and local air quality.

• Estimated install time: ~5 minutes per filter for most owners
• Recommended interval: every 12 months or ~12,000 miles
• Replace sooner in dusty or high-pollution environments
• Buying the kit reduces future ordering and service time

Who is this for?

This KAX CA11257 CF11668 kit is intended for owners and technicians who want a convenient, cost-effective way to service both the engine intake and cabin air system on compatible Dodge Charger, Challenger, and Chrysler 300 vehicles. It suits do-it-yourself drivers who prefer quick, reliable fitment without hunting for separate part numbers, as well as service shops that want a bundled solution to streamline routine maintenance and help keep engines and cabins performing predictably.
