Neither does the K&N drop in filter. Use the K&N filter and the stock airbox, you'll be fine with that for a while. If you want a short ram, just make sure that you get one that has a heatshield. Both the K&N and the SPT are sold in this configuration. Neither one is going to perform significantly better than the other, so it's going to be personal preference at this point.
I have the Perrin drop-in filter in my car and copped it for $26 on ebay. I also have a K&N short ram if you're interested.
My car is well, it's like 10 lbs of shit in a 5 lb bag...
