K&N Recharger Filter Care Service Kit
Maintain the performance of your reusable K&N air filter with the K&N Recharger Filter Care Service Kit, available with Red, Black or Blue filter oil.
K&N reusable oiled cotton air filters are designed to be cleaned and re-used rather than routinely replaced. Over time, dirt and debris collected by the filter can restrict airflow. The K&N Recharger Kit provides the cleaner and filter oil required to properly service the filter and help restore its airflow efficiency.
Complete K&N Air Filter Cleaning Kit
Each K&N Recharger Kit contains K&N Power Kleen Air Filter Cleaner together with a squeeze bottle of K&N air filter oil.
Power Kleen helps dissolve accumulated dirt, contaminants and old filter oil so they can be rinsed away with water. Once the filter has been completely dried, the supplied K&N filter oil can be applied before the filter is refitted.
Choose Your K&N Filter Oil Colour
This listing is available in three genuine K&N variants:
99-5050 – Red
Supplied with K&N’s traditional red filter oil.
99-5050BK – Black
Supplied with black K&N filter oil for applications where a darker filter appearance is preferred.
99-5050BL – Blue
Supplied with blue K&N filter oil for filters or installations where a blue appearance is preferred.
Select the required colour from the product options before ordering.
What’s Included?
Each service kit contains:
- 12 fl oz K&N Power Kleen air filter cleaner
- 8 fl oz K&N squeeze-bottle air filter oil
- Complete cleaning and re-oiling solution for compatible K&N filters
Why Service Your K&N Air Filter?
Reusable cotton air filters accumulate dirt as they perform their filtration function. Correct cleaning and re-oiling helps:
- Remove accumulated dirt and old filter oil
- Restore airflow efficiency
- Maintain the filter’s reusable cotton media
- Extend the usable service life of your K&N filter
- Avoid unnecessary replacement of a serviceable reusable filter
How to Use the K&N Recharger Kit
Remove the K&N filter from the vehicle and apply K&N Power Kleen to the filter media according to K&N’s cleaning instructions.
Allow the cleaner to loosen accumulated dirt before gently rinsing the filter with water. Leave the filter to dry completely naturally.
Once completely dry, evenly apply the supplied K&N filter oil to the cotton filter media. Allow the oil to wick through the material and check that the filter has been evenly treated before reinstalling it.
Do not reinstall or oil the filter while it is still wet.
Suitable for K&N Oiled Cotton Air Filters
The K&N 99-5050, 99-5050BK and 99-5050BL Recharger Kits are maintenance products intended for compatible K&N oiled cotton Filtercharger air filters.
They are not vehicle-specific parts, meaning compatibility is determined by the type of K&N filter being serviced rather than the vehicle make or model.
