The Suzuki DR-Z400S continues to impress in 2024 as a dual-sport icon, offering reliable power and trail-ready performance with its 398cc, liquid-cooled engine. One of the DR-Z400S's standout features is its left side body cover, which includes quick-release fasteners for easy access to the air filter—simplifying routine maintenance for every owner.
Why Air Filter Maintenance Matters
Your DR-Z400S's air filter serves as the first line of defense against dirt, sand, and debris. Regular cleaning and timely replacement are essential for engine durability, power delivery, and smooth throttle response. A neglected filter can lead to clogging, reduced airflow, and increased engine wear.
Recommended Air Filter Type
The 2024 DR-Z400S is designed to use a dual-stage foam air filter. Twin Air makes a popular replacement model for the DR-Z400S, featuring two layers of open-pore foam fused together to maximize filtration and airflow. The coarse outer foam catches larger debris, while the fine inner foam traps tiny particles—ensuring only clean air reaches your engine.– Suitable for Suzuki DR-Z400S from 2000-2024.
How to Clean & Inspect the Air Filter
- Remove the left side body cover using the quick-release fasteners for direct access to the airbox.
- Carefully detach the filter from the airbox. Inspect the sealing ring for a snug fit to avoid air leaks.
- Gently tap the filter to knock off loose debris. Use a designated air filter cleaner and follow with warm soapy water. Rinse thoroughly and allow to dry completely.
- Inspect for damage—such as tears, hardening foam, or separation of layers. Replace if compromised.
- After drying, apply air filter oil evenly for optimal particle capture. Ensure all areas are covered, but do not over-apply.
- Reinstall the filter, confirming seal contact all around.
Replacement Guide
- If the filter shows excessive clogging, physical damage, or reduced flexibility, replace it with an OEM or performance equivalent air filter.
- On the DR-Z400S, Twin Air's filter comes with a greaseless sealing ring for maximum contact with the airbox and uses an exclusively formulated adhesive to prevent seam breakdown.
- Always confirm fitment for the 2024 DR-Z400S before purchase.
Maintenance Schedule & Pro Tips

- The left side quick-release setup enables inspection and cleaning anywhere.
