When to Replace

Replace clogged or dirty filters when airflow is reduced or cabin air quality and driving comfort decline. A recommended maintenance interval is every 12,000–15,000 miles or every 12 months, depending on driving conditions. Dusty roads, heavy traffic, and seasonal pollen can increase filter loading.

Installation Tips

  • Verify the vehicle application and compare the replacement filters with the removed filters before installation.
  • Replace the engine and cabin filters in their correct housings; do not interchange them.
  • Follow the vehicle service information for access and removal procedures.
  • If an airflow-direction arrow is marked on a filter, install it in the indicated direction.
  • Close and secure each filter housing fully to help prevent unfiltered air from bypassing the filter.

FAQ

This kit is designed for 2018–2026 Chevrolet Chevy Equinox and GMC Terrain models with the 1.5L engine, 2018–2019 models with the 1.6L engine, and 2018–2020 models with the 2.0L engine. Confirm the engine and existing filter part numbers before ordering, especially on vehicles with multiple engine options.
The kit uses CF11966 for the cabin air filter and CA12260 for the engine air filter. The cabin filter replaces or cross-references with 23279657, and the engine filter replaces or cross-references with 84390002.
The kit includes one cabin air filter and one engine air filter. The cabin filter cleans air entering the passenger compartment, while the engine filter helps protect the engine from airborne dust and debris.
A restricted cabin filter may cause weak airflow, musty odors, or reduced heating and air-conditioning performance. A dirty engine air filter can contribute to reduced airflow to the engine, sluggish acceleration, or decreased fuel efficiency. Inspection is recommended if either symptom appears or if the vehicle is operated in dusty conditions.
Both filters are routine maintenance replacements and generally require no special tools. The cabin filter is accessed through the passenger-side dashboard or glove-box area, while the engine filter is installed in the air-filter housing under the hood. Allow approximately 15–30 minutes for both filters, and make sure the airflow-direction marking on each replacement filter matches the original installation.
