Shop parts for a 2022 Honda CRF450RWE Dirt Bike.
The 2022 Honda CRF450RWE – Works Edition – comes equipped with an advanced intake system that demands high airflow and maximum filtration for consistent performance. Keeping the air filter clean or replacing it at the right intervals ensures your engine breathes cleanly, preserves power output, and prevents internal damage. This MotoSport.com guide covers everything you need to know for effective air filter care tailored to your CRF450RWE.
Why Air Filter Maintenance Matters on the CRF450RWE
- High-performance motor: The CRF450RWE's engine is engineered for maximum power and sharper throttle response. A dirty or clogged filter restricts airflow, hampering performance and risking costly engine issues.
- Unique dual-stage filter design: This model uses a dual-layer foam air filter designed to trap both large debris and fine particles without restricting flow, making regular maintenance even more vital for challenging off-road conditions.
How Often Should You Service Your Air Filter?
- Clean after every ride in dusty or muddy conditions.
- Inspect after every ride even in clean conditions; clean or replace at the first signs of visible dirt or loss of performance.
- Replace the filter whenever you see tears, damage, or excessive wear that cleaning cannot fix.
Tools & Supplies You'll Need
- Fresh or cleaned OEM-style dual-stage foam air filter
- Filter-specific cleaning solvent
- Air filter oil (for foam type)
- Latex gloves
- Philips screwdriver and 8mm socket (for filter cage bolt and air box cover)
- Lint-free rags
Step-by-Step: Cleaning & Replacing the Air Filter
- Remove the seat & access the filter. Use the seat release to remove the seat. Unscrew the airbox cover if needed. The air filter is visible on the right side.
- Take out the filter. Unscrew and carefully remove the filter and cage assembly, preventing debris from falling into the intake.
- Clean the housing. Use a clean damp rag to remove dust or dirt from the airbox before inserting a new or cleaned filter.
- Clean the filter.
- Rinse the filter in an air filter cleaning solution, working dirt and oil out gently. Avoid wringing or twisting which can damage the foam and glued seams.
- Rinse with clean water. Allow the filter to dry completely.
- Inspect for tears or pre-mature wear. Replace if needed.
- Oil the filter (foam type).
- Saturate the filter with air filter oil, ensuring total coverage, then gently squeeze out the excess. The CRF450RWE's foam construction is designed to use oil for maximum efficiency.
- Reinstall – ensuring a proper seal.
- Attach the filter securely to the cage. Insert the assembly back into the airbox and fasten the bolt, ensuring an air-tight fit against the airbox rim to keep unfiltered air out.
- Double-check the foam sealing ring for damage or flat spots which could cause leaks.
- Reassemble. Install the airbox cover and the seat.
Model-Specific Tips for the 2022 CRF450RWE
- The 2022 CRF450RWE uses a high-flow, dual-stage foam air filter optimized for both maximum filtration and peak airflow to support its high-compression motor.
- Premium Works Edition models come with improved airbox tolerances; careful filter sealing is essential to leverage these benefits and prevent unfiltered air bypass.
- This Honda's filter cage and bolt are robust but should be checked for stripped threads or damage whenever the filter is serviced.

When to Replace
- If the filter foam thins, tears, or the glued seams separate – replace immediately for guaranteed engine safety.
- Always replace after a season of use, regardless of apparent condition, to keep your CRF450RWE at peak performance.
Final Notes
- Use only oils and cleaners designed for foam air filters to avoid damage to the specialized foam structure and adhesives.
