I think what it comes down to is what your looking for.. if u want that extra go down low the the air box with a good filter and some CAI would be the go.. but for that extra bit up top maybe the pod with a heatshield and CAI would do the trick? I think i'd prefer to have real nice mid/top range power because when ya want to go fast your at 80km/h real fast anyway and u still gotta hit that limmiter:P
I have gatehred some information from various people on this it doesn't solve much but brings some things to light.
"u do loose a bit of power down low but the power gain that i got topend with the pod was much better, but i think a properly set up air box with cold air running to it and a proper panel filter would probably be better. "
"POD's are a good investment for the mid-topend performance, but to be effective down low they need to be sealed correctly."
