K&N Synthetic Air Filter Cleaner & Degreaser Spray 32 oz — Restores Airflow, Emulsifies Oil & Dust

K&N Synthetic Air Filter Cleaner and Degreaser is a 32-ounce spray that dissolves grime and loosened debris from synthetic K&N air filters so they can be rinsed clean and restore airflow performance.

This concentrated spray is engineered specifically for K&N synthetic air filters to break down oil, dust, road film, and other contaminants that reduce airflow. The formula loosens embedded muck so you can rinse it away with water, helping the filter return closer to its original efficiency without aggressive scrubbing. Use it as part of routine maintenance to keep synthetic filters functioning reliably between replacements.

How does this cleaner restore air filter performance?

The spray penetrates and emulsifies oily residues and baked-on grime that clog filter media, allowing trapped particles to detach and be flushed away. By removing buildup, the filter regains more of its designed airflow and filtration characteristics.

• Targets oil and dust residues that reduce permeability
• Emulsifies grime for easier rinsing with water
• Designed to work on K&N synthetic materials without damaging the media

When should I use the 32 oz spray on my K&N synthetic filter?

Clean the filter when you notice reduced airflow, visible dirt accumulation, or as part of scheduled maintenance after heavy use in dusty environments. The 32-ounce spray provides multiple cleanings for most filters, suitable for car, truck, and powersports applications.

• After off-road or dusty driving conditions
• When airflow feels restricted or during yearly service
• Before re-oiling synthetic filters if required by the filter care procedure

Is this safe for all K&N synthetic air filters and how do I apply it?

This cleaner is formulated specifically for K&N synthetic air filters and should be safe when used according to instructions. Apply the spray to both sides of the filter, let it soak briefly, then rinse until water runs clear and allow the filter to dry thoroughly before reinstalling or finishing any reconditioning steps.

• Spray evenly across filter pleats and surfaces
• Allow dwell time to loosen contaminants, then rinse with low-pressure water
• Dry fully before reinstalling or completing any re-oiling if applicable

What practical benefits will I notice after cleaning with this degreaser?

After proper cleaning and drying, expect improved airflow through the filter and a cleaner filter appearance. While performance will vary with filter age and condition, removing built-up debris helps the filter operate more closely to its original design.

• Cleaner filter media for more consistent airflow
• Removes trapped contaminants that hinder performance
• Supplies enough cleaner for several maintenance cycles

Who is this for: Vehicle owners and technicians who use K&N synthetic air filters and want a purpose-made cleaner to remove oil, dust, and road grime. It’s suitable for motorists, off-road riders, and small-engine users who perform filter maintenance themselves and prefer a product formulated to preserve synthetic filter media and restore airflow efficiency.
