aiyah, open pod, close pod, it all depends alot on your right foot, of course with proper vantilation to your filter, you will get better performance + lower fuel consumption. taking in the fact that your carb is properly tuned, as now im trying out back my original filter, doesnt seems to make a large diff, the consumption is hard to say but it certainly looks the same as when i was using the open pod + customed DIY-ed surbo air ram. so erm,i dunno lorr, maybe its your choice, most prob ill be going back to open pod later as i know the open pod is better higher RPM when your car sucks in air like a whale sucking in water :) maybe i can tell you the difference later when i have fully tested the original filter, as i never really used it before. got the car and i immidietely changed it to the open pod as the first time i drove up the car to genting, wow, cannot climb...so bye bye original filter and hello open pod :D this was because i alwiz had to remove the filter when going genting and i was sick of it(actually i oni removed the filter once :lol: but it was bad enough i had to remove it as the first time, the car refuse to climb above 4K-5K RPM :lol: )
