There is a standard shaped K&N and a conical. In order to install the conical you will need an adapter or kit. I went to the local speed shop and picked up an adapter plate for my V6 for about $15. The conical is a little noisier (albeit a COOL kind of noisy) and it will give you a constant CEL, but you'll notice the added punch. In my opinion the conical is the way to go. It's also not much more expensive.
