K&N Large Air Filter Service Kit — 32 oz Cleaner, 12.25 oz Red Oil & 2 Stickers for Reusable Filters

K&N Large Size Air Filter Service Kit includes a 32 oz. cleaner/degreaser, a 12.25 oz. aerosol red oil, and two K&N stickers to keep reusable filters performing like new.

Routine cleaning and correct re-oiling are the simplest ways to extend the life of a reusable air filter while preserving airflow and engine responsiveness. This service kit supplies a concentrated spray cleaner to remove trapped dirt and oil, plus a ready-to-use aerosol red filter oil formulated for even coverage. The package also includes two K&N stickers tucked under the oil cap to identify the filter as maintained.

How will this kit help maintain my reusable air filter?

The components are designed to work together: the cleaner lifts and dissolves embedded grime, and the oil restores the filter's particle-trapping surface. Regular use prevents clogged pleats and sustains airflow characteristics engineered into the filter element.

• 32 oz. spray cleaner/degreaser loosens dust and contaminants for thorough rinsing.
• 12.25 oz. aerosol red oil provides uniform coverage in seconds.
• Cleaner and oil preserve the filter's designed air/fuel balance and longevity.

How often should I clean and re-oil my K&N filter?

K&N recommends cleaning the filter at regular intervals depending on driving conditions and re-oiling after it dries. For many applications, cleaning every 50,000 miles and re-oiling every 10,000 miles is a practical baseline, but severe dust or off-road use requires more frequent service.

• Standard guidance: clean approximately every 50,000 miles under normal conditions.
• Re-oil roughly every 10,000 miles to maintain filtration efficiency.
• Increase frequency in dusty, sandy, or high-pollution environments.

What exactly comes in the package and how is it used?

The kit includes a ready-to-spray cleaner, an aerosol red oil, and two K&N stickers. Use the cleaner to soak and rinse the filter, allow it to dry fully, then apply the aerosol oil sparingly and evenly to restore filtration properties. Stickers are provided for identification and warranty/reference purposes.

• One 32 oz. cleaner/degreaser spray bottle for thorough washing.
• One 12.25 oz. aerosol can of red filter oil for quick, even application.
• Two K&N stickers placed under the oil cap when the order arrives.

Can I use these products on any K&N reusable filter size?

This large-size service kit supplies enough cleaner and aerosol oil for commonly sized K&N filters and multiple cleanings. Verify the filter size and consumption rate; heavier or repeated cleanings may require additional cleaner or oil.

• Formulated for K&N reusable filters; volume suits large filters and multiple services.
• Supplemental cleaner or oil may be needed for very large or heavily soiled filters.
• Follow K&N cleaning instructions to achieve best results and avoid over-oiling.

Who is this for: The K&N Large Size Air Filter Service Kit is for vehicle owners and hobbyists who use washable K&N filters and want an easy, manufacturer-recommended way to clean and re-oil them. It's ideal for drivers who value reusable filtration, long-term cost savings, and maintaining consistent engine airflow—particularly those who perform their own routine filter maintenance, service multiple vehicles, or own larger air filters that require more product per service.
