I got a used K&N drop-in last night in the mail, and cleaned it last night...let it dry overnight.
I oiled it this morning before I got in the shower. Let it soak for about 30 min while I got ready and made lunch etc.
Put it in my car, everything seemed fine. I gunned it as I pulled out of my apt. complex and got a CEL.
After I got to work, I checked on the K&N, and pulled it out...there was a LOT of moisture. I shook it, and droplets came flying out.
Luckily I still had my stock air filter in the car. I put it back in and started it up and still had a CEL.
Is this really going to screw $h1t up?
