Can this be used for cleaning the air filter of a car like for 33-2370 filter model of K&N?

Offcourse it can be used. The material of filter is the same. The design only differs. ONLY thing to note is that the filter should be washable and reuseable type. The filter type should be oiled filter. If its dry filter then you can use the spray to clean it only. just do not oil it once cleaned. Hope this is helpful
