Maintaining a clean air filter is crucial to the performance and longevity of your 1987 Yamaha XT350.

What You Need to Know About the XT350 Air Filter
- Two-stage foam filter: The XT350 uses a replaceable dual-layer foam air filter (OEM part number 30X-14451-00) for superior filtration.
- Access location: The air filter is housed in the airbox beneath the seat and right side panel—removal requires basic hand tools.
- Frequency: Clean after every ride in dusty conditions; replace at least annually, or more often if the foam shows wear or tears.
Air Filter Cleaning Instructions
- Remove the seat and right side panel using appropriate tools.
- Take the airbox cover off and gently remove the foam air filter.
- Inspect the filter for tears or excessive degradation—if damaged, replace immediately.
- Wash with a cleaning solution formulated for foam air filters (biodegradable "clean in water" cleaner is compatible with many aftermarket filters). Avoid gasoline or harsh solvents.
- Gently squeeze (do not wring) the foam until all dirt and oil are removed—repeat as needed.
- Let the filter dry completely away from direct sunlight or heat sources.
- Saturate the clean, dry filter evenly with fresh foam air filter oil. Massage to distribute oil throughout the foam layers.
- Reinstall the filter, ensuring a snug seal around the airbox rim. Check the airbox for debris before installation.
- Reassemble the airbox cover, side panel, and seat.
Replacement Guide
- Verify specs match XT350 1986-1989 filters; quality options feature coarse and fine open-pore construction.
- Replace the filter if physical damage or worn foam is detected—compromised filtration risks engine damage.
- Use OEM or high-quality aftermarket replacements compatible with the XT350.
