There is advantage and disadvantage I heard about open pod filter. Some say at the beginning, you will feels that the car response very well but after a while you will start to encounter loss of power although suction sound is loud. Open pod is suppose to allow better air flow but then it also can cause excessive air flow without proper tuning and proper mod.
Kalau dah menyorok dalam box, no more open pod la bang. Dah jadi macam drop in loading..he he
