Well..socks would be the easiest way to go but doesnt NA engines perfer colder air over more volume...? i can see how 4 socks would have a larger surface area for the air to be sucked in compared to my current BMC CDA, but its kinda hard to direct cold air to that area... if i did go socks i'd have to make up heat shield to block the hot air... I'm really struggling... there's this nice set of individual K&N filters that bolts straight up to the throttles but i'm kinda worried about the performance advantages too... Which one u recon would make more power....?
