Any enclosed box intake is a good one. Refrain from open filter intakes that do not have any true cold air guided in.

 

i like something closed like the factory airbox. like an s&b or something.

edit: haha darren you me are on the same page

 

I wish Troyer was. The AF1 was one of the things that attracted me to buying their kit. But I was informed two days ago by them that they no longer have them b/c they went out of business. So now Troyer is providing the Airaid model with their kits. After all the reading about the two kinds on here I'd rather have the AF1 but no such luck. :o
