Synthetic Air Filter Cleaner and Degreaser: 32 Oz Spray Bottle; Restore Engine Air Filter Performance, 99-0624

Cleaned both my k&n filters great. Would buy again.

WORKS GREAT EASY TO USE!

I’ve been using K&N reusable air filters for years, and this cleaner and degreaser does exactly what it’s supposed to. The spray bottle makes application quick and easy, and it cuts through built-up dirt and oil without a lot of scrubbing. After rinsing and letting the filter dry, it looks noticeably cleaner and airflow improves. I like that it’s specifically formulated for synthetic filters so there’s no worry about damaging the material. One bottle lasts a long time, making it much more economical than buying replacement filters. If you maintain K&N filters, this product is a must-have.

Bought this as it is the recommended cleaner from Banks Power for my air filter. It does the job and cleaned the filter out so I can keep using it.

I have used K&N for a number of years in my truck. I like their products and this is no exception. Cleaned the air filter quickly, rinsed, and set out to dry and re oil. Just be careful not to let it sit too long. The cleaner shouldn't be allowed to dry on the filter before rinsing.

Works great I’m cleaning the filters on my brother

I have an AEM synthetic air filter cone on my Mazda's short ram. While AEM used to market their own cleaning kit, they now suggest using this K&N cleaner. I can see why. The old AEM kit cost more, used a lot more chemicals, and soaked the filter to such an extent that it took forever to dry. With the spray bottle you can use less cleaner, but can apply it better and get the same results. Cleaned it at night and put the filter back on in the morning. Fortunately (or unfortunately) it cleaned the filter so well that the engine computer interpreted it's new easy breathing as a fault and threw the check engine light on. You can fix that on most cars by disconnecting your battery for less than a minute. You'll have to reset your radio settings though.

This size provides enough cleaner to ensure a good cleaning of the air filter. Smaller volumes barely get the job done.
