How often should you clean the filter. I put my AEM CAI back when I had 2000 miles on my car... now i'm up to 6000, but the filter looks blue (maybe from some spilled windshield washer cleaner?) should I clean it now or wait until later? The only reason I ask is that I'm going to be going on a trip of at least a thousand miles and I'd like my car to run really well for the trip. Thanks

I've been doing my AEM short ram filter at 6000 mile intervals, but since your cold air is practically riding on the ground you might want to try 4000 mile intervals.
It depends on how wet and dirty your roads are. The blue is not a good sign. You should be able to see the red K and N filter oil.
