Installation Guide

1. Locate the Cabin Air Filter Compartment: Usually found behind the glove box or under the dashboard on the passenger side.
2. Open the Compartment Cover: Gently lift or slide the cover to expose the filter housing.
3. Remove the Old Filter: Slide out the existing filter, noting its orientation for correct placement of the new one.
4. Insert the New Filter: Place the CU 2521-2 filter into the housing, aligning it with airflow direction indicators (often marked on the filter).
5. Secure the Cover: Close and lock the compartment cover to ensure a tight seal.

Repeat the process for the second filter in the set if your vehicle requires dual filtration. Regular inspection—every 12,000–15,000 miles or as recommended by the manufacturer—is advised to maintain optimal performance.
