K&N Synthetic Air Filter Cleaner & Degreaser 32 oz Spray — Restores Airflow, Safe for Synthetic Media

K&N Synthetic Air Filter Cleaner & Degreaser (32 oz) is a ready-to-use spray formulated to dissolve grime and oil from synthetic air filters so clogged debris can be rinsed away and airflow restored.

Keep your engine-breathing parts working efficiently by removing accumulated dirt, oil and road film that restricts airflow through synthetic K&N filters. This 32-ounce spray is designed specifically for K&N synthetic filter media and loosens contaminants so they can be flushed clean with water, helping the filter regain near-new airflow characteristics without damaging the media or seals.

How does this cleaner get contaminants out of synthetic filters?

The formula penetrates and breaks down oily residues, road grime and particulate build-up so trapped muck no longer bonds to the fibers. After spraying and allowing dwell time, the loosened material rinses away with a gentle water flow, leaving the synthetic media clear.

• Ready-to-use 32 oz spray bottle for easy application
• Degreasing agents formulated for synthetic K&N media
• Short dwell time loosens stubborn deposits
• Rinses clean with water—no harsh scrubbing required

Will this harm my K&N synthetic filter or seals?

No—this cleaner is formulated for synthetic K&N air filters and is intended to be safe for the media and filter components when used as directed. It avoids harsh solvents that could degrade filter fibers or bonding agents.

• Developed for K&N synthetic filter materials
• Non-abrasive action preserves filter structure
• Safe for seals and gaskets when rinsed thoroughly
• Follow label directions for best results

How do I use the 32 oz spray to get the best results?

Spray the cleaner liberally onto both sides of the filter and allow it to penetrate for the recommended dwell time. Rinse with low-pressure water from the clean side out until runoff is clear, then allow the filter to air-dry fully before reinstallation or re-oiling if required by your filter model.

• Spray evenly across dirty areas and let sit to loosen grime
• Rinse from clean side to dirty side to push debris out
• Air-dry completely before reinstalling or treating
• Use with K&N oil products on filters that require oiling

How often should I clean my synthetic air filter?

Cleaning frequency depends on driving conditions and environment—inspect the filter periodically and clean when you notice visible buildup or a drop in airflow. In dusty or off-road conditions you may need to clean more often than in light urban driving.

• Inspect at recommended service intervals or after heavy use
• Clean when dirt visibly clogs the fibers or airflow drops
• Frequent checks in dusty environments are advised
• Use K&N cleaner between major service intervals to maintain performance

Who is this for: K&N Synthetic Air Filter Cleaner & Degreaser is ideal for vehicle owners, mechanics and enthusiasts who use K&N synthetic air filters and want a straightforward, manufacturer-focused cleaning solution. It suits anyone who prefers a spray-on, rinse-off maintenance routine to restore filter airflow and extend filter life without replacing the media frequently.
