K&N Power Kleen Air Filter Cleaner & Degreaser — 1 Gallon Concentrated Cleaner for Oiled Cotton Filters, Restores Airflow

K&N Power Kleen is a heavy-duty cleaner and degreaser formulated to remove old oil, grime, and trapped dirt from oiled K&N cotton media air filters so they can be rinsed and returned to optimal airflow.

When you rely on a reusable oiled air filter, periodic cleaning is essential to maintain airflow and filtration efficiency. Power Kleen is purpose-built for K&N cotton-media filters: it dissolves the oily residues and suspended contaminants that clog filter pleats, rinses away with water, and helps restore the filter’s original breathing capacity. Using other solvents—especially gasoline—or unapproved cleaners risks damaging the cotton media and may void the manufacturer warranty.

How does Power Kleen remove old oil and trapped debris?

Power Kleen works as a concentrated degreasing solution that penetrates the filter media to loosen oil, soot, and lodged particles. After soaking and agitating, the dissolved contaminants rinse out cleanly, leaving the pleats ready for re-oiling and reuse.

• Concentrated formula breaks down oils and hydrocarbons.
• Penetrates deep into cotton layers for thorough cleaning.
• Rinses away with ordinary water—no harsh scrubbing needed.
• Safe for K&N oiled filters when used as directed.

Will Power Kleen restore filter airflow and performance?

By removing accumulated grime and old oil, Power Kleen helps return the filter’s airflow characteristics closer to original condition. Restored airflow supports the engine’s intake efficiency without altering the filter’s intended filtration properties when re-oiled properly.

• Reduces pressure drop caused by clogged pleats.
• Helps recover near-new breathing capacity after cleaning.
• Designed to work with K&N re-oil for correct filtration balance.
• Not a substitute for mechanical inspection; always check for damage.

Is Power Kleen the right choice for my K&N filter—and how do I use it safely?

Power Kleen is the only cleaner recommended by K&N for their oiled cotton filters; other solutions can harm the media and risk voiding warranty. Follow the label instructions: apply, soak, rinse thoroughly with low-pressure water, and let the filter dry completely before applying the specified filter oil and reinstalling.

• Use only on oiled K&N cotton-media air filters.
• Avoid contact with polished or anodized aluminum surfaces.
• Never clean filters with gasoline or non-recommended solvents.
• Ensure full drying before re-oiling to prevent over-saturation.

How much product do I need and where does this gallon size fit in maintenance?

A one-gallon container supplies multiple cleanings for cars, trucks, motorcycles, or small fleets—ideal for regular maintenance intervals. It’s a cost-effective option for enthusiasts and shops that service several reusable filters, reducing trips to buy smaller bottles.

• One gallon covers many cleaning cycles for individual vehicles.
• Useful for home mechanics, performance shops, and fleets.
• Store in a cool, ventilated area away from incompatible materials.
• Follow local disposal guidelines for any used cleaning residues.

Who is this for? K&N Power Kleen 1-gallon is intended for owners of reusable oiled K&N cotton air filters: car and truck enthusiasts, motorcycle riders, automotive shops, and fleet managers who want a manufacturer-recommended cleaner to keep filters functioning properly. If you maintain multiple filters or prefer fewer purchases, the gallon size delivers value while ensuring you use a product designed specifically for K&N media. Always follow K&N’s cleaning and re-oiling instructions to preserve filtration integrity and warranty coverage.
