Air Filter Access – 2015 KTM 350XCF
KTM designed the 350XCF with ease of maintenance in mind. The air filter is quickly accessed from the left side by removing the seat and airbox cover, featuring a tool-less system for rapid service. This design feature is unique for this model year and helps reduce downtime between rides.
Recommended Air Filter Type
- The stock filter uses a dual-foam element for effective filtration and airflow balance.
- Washable cotton-gauze aftermarket options, like K&N Xstream, are compatible and offer enhanced reusability and airflow while retaining dust-trapping efficiency.
Cleaning the Air Filter
- Remove the seat by pulling up at the rear and lifting free.
- Take off the airbox cover by releasing the latches.
- Release the air filter – no tools required. Gently pull the filter element out.
- Inspect for excessive dirt, damage, or oil saturation. A severely soiled or damaged filter should be replaced.
- Wash the filter using filter-specific cleaner or mild soap (no gasoline or harsh solvents). Rinse thoroughly with water and squeeze gently – do not wring or twist.
- Dry completely – let the filter air dry away from direct sunlight or heat.
- Apply air filter oil evenly over the entire surface, ensuring all foam pores are saturated but not dripping.
Reinstalling the Filter
- Confirm the airbox is clean and free of debris.
- Insert the filter element securely in place to create an airtight seal. Faulty installation can allow dust ingestion, so double-check the fit.
- Secure the airbox cover and reinstall the seat.
When to Replace Your Air Filter
- If the foam is torn, breaks down, or remains dirty after proper washing
- After several cleans (as foam can deteriorate over time)
- If using the cotton gauze type, refer to manufacturer guidelines for service intervals
