I would think a mild laundry soap, you could at least try buying the cleaning kit online

 

To be honest, I used just plain water and my fingers to get out larger pieces of dirt. I have the dry-flow filter too. After cleaning it under running warm water, I let it dry for a few hours. It's been fine ever since. But this thread reminds me I need to clean it again. I clean mine every 2 months or so, basically every other oil change.

 

Don't forget you should rinse the filter from inside out so you drive any stuck particulates deeper into the filter material.
Before I got my dryflow, I used to have an elcheapo cotton, which I cleaned with simple green. I wouldn't see my you couldn't do the same. Spray down the outside, let it sit for a little while and then flush from the inside out and let thoroughly dry. I've only had my dryflow for a couple of months now so haven't had to clean it yet (plus it's a LRI beside the battery so doesn't get so dirty...)

 

i was thinking about getting one for my intake... are they worth the extra money?? is the dryflow really that good?? is it worth it??

 

check ebay, i've seen some cleaning kits on there

 

Are they worth the extra money? I say yes, because to really have a quality filter, you'll either pay the AEM price, the K&N price, and if you're really loaded, then an HKS Megafilter price.

The fact that all you really have to do is rinse it out/off and let dry really works for me. I don't like having to oil filters, it bothers me for some reason.

You should get one. I'm at a higher altitude since my move, but my car doesn't seem to mind the thinner air, and I can probably attribute some of that to the filter itself.

 

It's probably a good thing for MAF equipped cars vs oiled filters.

 

+1 to running it under water from the inside out. That has worked well for me. I bought the AEM kit from a tuner shop for $10, and it smells like citrus cleaner. Bubbled up like it, too.
