I was surfing the web looking at car stuff naturally, and I found a cabin air filter for my corolla. The part # is VF- 2000 $40 but I could only find it at autozone but that's ok with me, I've had it in the car for a week now and it's all good it doesn't stink at all. So now with the K&N air filter in too I hope to save a chunk of money in the long run.
