I have an AEM V2 CAI with the dryflow filter on it & just am looking for input on cleaning interval from others who have one. I get that it depends on climate, location, driving conditions, etc., yadda, etc., but I'm wondering about the AEM specs. I put mine in last August, so its been about 14 months and I'd say around 18,000 miles. AEM claims on its website that the dryflows can do fine w/o cleaning for 50k to even 100k miles. Man that seems high. But I don't want to deal with the hassle of snaking that thing out of there if I don't have to. Can anyone verify - are those filer elements really just fine all the way up to 50,000 miles with no cleaning attention?
