6637 Filter How Often Do You Replace?
I have been running my 6637 filter for almost a year now, how often do you change? I am going on a long road trip next week and I figure for the best mileage I should put in a fresh filter. I know these filters are not expensive but has anyone blown them out with an air compressor? We used to do this with some of the tractor filters we used on the farm?

It all depends on where you live. Dusty environments require more frequent filter changes. Check it like you would any other filter. Take it off the intake tube and hold it up to the light. Look inside the filter and if there isn't much light passing through, then it's time to replace.

I have had mine for almost a year and it still good. I do alot of driving on dirt roads so I blow mine out on a regular basis, but like Pocket said just keep checking it for blockage.

Once a decade should work. But then again I only put about 1k-2k a year. Good advice above. I don't think I'd go with the filter minder because by the time it lets you know it's bad it probably would be a decade regardless of mileage. Pretty sweet filter.

Yup. Last time my stock filter was clogged.
Went to Texas to buy truck. Drove it away from the broker, and the engine ran fine. Stopped for fuel. Popped hood and found FilterMinder pegged. Re-set it and ran the truck to the hotel for the night. Found it pegged again. Filter was filthy. Previous owner hadn't looked at it for a while, THAT was obvious!
Changed filter, ran it all the way from Texas to California. 'Minder never flinched. Decided they worked as advertised, so bought one for the wife's Odyssey minivan, too.
I'm a believer.

Speaking of filters, I just converted my K&N open filter to the baldwin 2818, using the K&N tube, it actually fit well. I was wondering not about the Filter Minder, but the small probe that was in the side of the K&N box. Thanks for any help. I have it just laying underneath the filter now.

Not sure if I would clean them...
I may be barking up the wrong tree here, but I really don't think I would try to save $25 to try to clean one of the paper filters.
Reason #1. The dirt that gets in there is most likely dirt or sand like and abbrasive. Meaning if you try to blow high pressure air from the outside in, it would likely force the dirt into the filter, tearing holes in it making it less effective as a filter media.
Reason #2. If you were able to blow air inside and pressureize it and blow the dirt out, the flow of air in the reverse direction may also tear the paper or make any holes in the paper larger, and allow biger particles to get into the turbo. I had mine on there for a little over a year with 10,000 miles on it and it was greyish colored but far from filthy but I changed it anyway. Just my 2 cents worth...it may not be worth that, but I just would not spend the time or take the chance of dusting the turbo...

Mine was plugged up in 3 months, take in mind though my truck goes through dirt roads all the time since i live in the middle of the woods, and these road can get quite dusty. I ordered a new one though and i dont care that it only lasted 3 months since it is filtering 10 times better than that stock leaky airbox.

Keeping in mind that a used filter actually filters better than a brand new one, it's easy to see why a "restriction gauge" of some kind is the only good way of telling when the filter actually is no longer doing its job.
I don't "clean" a filter with compressed air. I would suspect that the initial flow afterward might be kinda' "gritty". I just run the air through the medium in only one direction until it degrades to a certain, pre-determined point. Then I replace the filter.
