Yup, cut the plastic out, and the air can flow through the grille and into the snorkle. I ended up doing what douggie did and getting some RV sewer hose from wal mart, it was like 3 bucks. I took off the snorkle, left the long verticle chamber, (I think its a preventitive measure in case water made it that far... its got a hole in the bottom to let the water out possibly, I live where the streets turn to small rivers, and dont want the dreaded hydrolock) I took the sewer hose and ran it to the same location a CAI would be, by the tire. If it rains hard enough to make me worried, I can just pull the sewer hose off the 90 that is facing up, so its more like a SRI. I was in the same boat as douggie, couldnt get it to chirp into second, now it can. it also goes pufff-vroooooom louder, and thats as good as an APC sticker as far as HP goes lol.
