All depends on your preference and where you live. If its dry and dusty you may or may not want to go for an oiled filter.
I made a short ram air intake for my friends Hemi Ram using a Specter cone. Works great! You can checkout Green Filters too or K&N

AEM makes dryflow filters but the catch is that they are more restrictive than cotton-oil filters. just go with an s&b powerstack top. visit there site for the right fit to your intake. dust aint an issue up in norcal from my experience so you can afford a low restrictive filter like cotton-oil.

Oiled filters? Why is this necessary?
No need to compromise low restriction for efficiency and engine protection.
Why oil a cheesecloth air filter? Regardless of manufacturer (and they are all fundamentally the same), why is this necessary in the first place? Oiled gauze filters afford low restriction when new or clean. Once loading occurs, the restriction curve rises almost vertically. Plus, they hold very little dust so maintenance is often required. What good is a performance filter if it only works as designed when new? How long does it remain in that condition?
Whenever a switch is made to a oiled cotton air filter, efficiency and engine protection are always sacrificed. In most cases, factory paper filters are approx. 98-99% efficient. Gauze, on its best day, is 95% and each time it's cleaned and oiled, the orientation of the fibers changes and it soon becomes even less efficient. In many cases, efficiency enters the high 80% range. This assumes that an even distribution of oil is applied. Too much is a problem and if you miss a spot, the gauze does almost nothing on its own. Regardless of where you live, dust is an issue. It contributes to significant wear and is the leading cause of engine oil breakdown.
It required a great deal of time engineering a performance media that maintains extremely low restriction when new and dramatically improves restriction performance once loading begins when compared to competitive products. Plus, oiling and solvent cleaning are never required!
It may be prudent to evaluate the choices once again and ask what's best when all of the important categories of filtration are considered.

so aside from your product. What do you recommend? Are you willing to do a group buy special? I'm interested, I think something fell on mine before I installed it and crushed it a little. I was planning on getting a cheap $30 from Autozone

We can set up a group buy on the replacement filters.
Take a look at the loading graph on our web site and you can determine the performance and efficiency comparisons of many filters.
The tests we conduct are based on SAE/ISO 5011 protocol and can be repeated anywhere in the world. The tests rely on standard air or SCFM rather than using random characteristics. We also test with fine dust rather than coarse. This represents real world conditions and fine is much more difficult to trap than coarse. We also count the amount of particles that go through a filter as well as determine the size in microns ranging from 5 to 1 micron and below. Unlike the majority of intake manufacturers, we manufacture our own filters and intakes and do so in our Forest Park, IL facility.
The majority of our filters utilize a 6" outlet with a shaped radius and a venturi rather than clamp onto a tube.
Thanks
