thats not true. Pod filter is only illegal when it is exposed fully if there is an effort to cover the filter by about 80% this will make it legal. my car is supercharged so the filter hangs behind the front bar covered on 1 side by custom air box to protect from water, can't put cold air induction down there(no room). however the power gains are very debateable. If your not supercharging and you have to use one, i would be going cold air induction all the way by people like SS inductions full on kits for nearly every commo with dyno proven results.
