The 2016 Suzuki DRZ400SM remains a top choice for supermoto fans, appreciated for agility, reliability, and straightforward maintenance. One critical service task is keeping the air filter clean or replacing it as needed. A clean filter safeguards the engine against dirt, dust, and debris—especially vital for a bike that sees mixed street and off-road use.
How Often Should You Maintain the Air Filter?
- Inspect the air filter every oil change (about every 3,000 miles), or more often if riding off-road or in dusty locations.
- Replace the air filter if it appears excessively dirty, torn, or fails to clean up fully. Popular options include Twin-Air 153156 replacement filters for the DRZ400SM.
Tools & Products You'll Need
- Air filter-specific cleaning solution (foam filter cleaner recommended)
- Garden hose
- Foam air filter oil
- Lithium soap-based grease (for sealing the filter lip)
- Clean rags
Step-by-Step Cleaning Instructions
- Remove the seat and access panel to reach the air filter. On the DRZ400SM, release the side panel "pin" and slide the filter out carefully.
- Inspect the filter. If it looks intact but dirty, proceed to clean. If it's torn or crumbling, replace it.
- Rinse off excess dirt using a garden hose. Soak the filter thoroughly.
- Spray cleaner on the filter, inside and outside. Allow the cleaner to sit for several minutes to loosen dirt.
- Rinse the filter from the inside out to drive debris away from the filter foam. Repeat until water runs clear.
- Air dry completely. Let the filter sit for at least 5–10 minutes until no moisture remains.
- Apply foam filter oil evenly to every crevice of the filter. Squish (do not wring) out excess oil—this ensures full coverage without saturation.
- Apply a thin layer of lithium soap-based grease on the filter's inner sealing lip for a perfect seal.
- Reinstall the filter in the air box, followed by the cover and seat.
When To Replace the Air Filter
The OEM foam filter on the DRZ400SM is durable but should be replaced if it's damaged, shows heavy wear, or won't clean up fully. Opt for reputable aftermarket replacements like Twin-Air 153156. Frequent replacement is recommended for aggressive riders, especially those who tackle dusty or off-road conditions.
DRZ400SM Notes & Tips
- The SM model's air box is identical across several DRZ variants—use manufacturer-approved parts for best performance.
- Ensure the filter is properly dried and oiled before installation. A wet or under-oiled filter increases risk of engine damage.
- Lubricate the sealing surface to enhance fit and prevent unfiltered air entry.
- Monitor engine response after filter service; improved throttle and smoother idle indicate good airflow.
