So took my intake off for smog, passed it. Now I wanna put it back on and I never cleaned my filter, there is no convenient store that sells the AEM dryflow cleaning kit plus I don't wanna spend 10 bucks on it when I can use an alternative. Have you guys used anything else?

 

soap and water. let air dry. reinstall.

 

I used some concentrated detergent, just poured a little on the bucket and did the job just fine.
