which is better
Im sure the K&N works well, but most of the guy on this site just get a lid, and a cotton filter. (i think cotton is good for +1-2 hp over paper). Lids are cheaper. MUCH cheaper.
And I would stay away from the oil filters. I remember one guy at camaroz28.com dynoning his car with a paper filter and an oil filter and the oil filter caused him to lose 2 horses and 3 torque. And he is most definatly not the first person to say that he did not like them on LS1's.
