Are they washable a la K&N and other rechargeable brands, if so is there a recharge kit like there is for K&N? I have the K&N kit, but it's a red liquid and the Nismo filters are white....

mine are dutty.

 

Hmmm my Nismo filters are black? Wonder what the difference is.

Yup they are from what I've read here that Nissan sources the filters from aem not sure that is true but I've washed and cleaned my nismo air filter 3 times already since buying the car with 20000 miles (now 89k).

 

I've only washed mine twice since i got it last yr. Tooth brush bristles work for me.
