KAX Engine & Cabin Air Filter Kit for Audi 2.0L — CF11179 + CA10522, charcoal cabin & pleated engine filter

KAX CF11179 CA10522 is a two-piece replacement kit combining an engine air filter and a charcoal cabin air filter designed to restore engine breathing and reduce in-cabin odors for compatible Audi models.

This kit bundles the engine air filter and the cabin (HVAC) air filter into one convenient purchase, engineered to match the fit and airflow needs of several Audi 2.0L gasoline models. Each filter uses multi-layer media and coconut shell-activated charcoal in the cabin unit to trap particulates and neutralize unpleasant smells, while the engine filter helps protect intake components from dust and debris. The package is boxed and sized for straightforward installation with basic hand tools.

Which Audi models will these filters fit?

The KAX CF11179 (engine) and CA10522 (cabin) are specified for a range of Audi platforms that use 2.0L engines and particular HVAC housings. Confirm fit by comparing dimensions and OEM part numbers with your vehicle’s service manual or existing filters before ordering.

• Compatible: Audi Q5 (2011–2017) 2.0L
• Compatible: Audi A4/A4 Quattro (2009–2016), including Base/Prestige/Komfort/Premium/Plus trims
• Compatible: Audi A5/A5 Quattro and Audi allroad model years noted (2010–2017 variations)
• Specification check: engine filter 12.7" x 5" x 2.6" rectangular shape

How do these filters improve daily driving and maintenance?

Replacing both filters at the same time preserves airflow balance and reduces the chance of leaving one neglected. The engine filter helps keep intake passages and sensors cleaner, while the cabin filter improves air quality and reduces odors inside the vehicle.

• Engine protection: traps dust and road particles to reduce wear
• Cabin comfort: activated charcoal reduces smells from traffic and HVAC
• Time-saver: two-in-one purchase means fewer orders and fewer service visits
• Quick install: designed for a five-minute swap with common tools

What are the construction and material highlights?

Both filters use layered filtration media; the cabin filter integrates coconut shell-activated charcoal for odor control, and the engine element is built to balance filtration efficiency with airflow. These are single-use disposable filters packaged in a protective box.

• Cabin: multi-layer media with coconut shell-activated charcoal
• Engine: pleated filter media sized to OEM-equivalent dimensions
• Non-washable and not reusable—replace per maintenance schedule
• Boxed packaging protects filters until installation

How should I replace and care for these filters?

Installation is straightforward: remove the old filters from the engine intake and the HVAC housing, then install the new KAX filters in the same orientation. Follow vehicle-specific access steps in your owner’s manual, and dispose of used filters responsibly.

• Turn off vehicle and locate existing engine and cabin filters
• Remove clips or screws holding housings; take note of filter orientation
• Install new filters in the identical position and reseal housings securely
• Replace at regular intervals or sooner in dusty environments

Who this is for: This KAX CF11179 CA10522 kit is aimed at Audi owners who prefer a single, matched replacement for both engine and cabin filters—drivers seeking straightforward upkeep, noticeable cabin odor reduction, and OEM-style fit for 2.0L Audi Q5, A4, A5, and allroad models within the listed years. It suits DIY enthusiasts and technicians who want a quick, boxed solution to routine air-filtration maintenance without mixing brands or skipping the cabin filter.
