Hi guy's, As far as water goes it's not a problem. Drove my car down to melbourne saturday the weather was as bad as you would possibly get. I drove it behind cars trucks getting a full face of road spray the rain was pelting down all the way, it's about an hour and a half travel time. I pulled up at the dyno shop and removed the shaker scoop and filter to see what had happend and see where the water went. The results were that there was some water laying in the water trap, the filter was slighty damp but there was absolutely now water anywhere under the filter. It was bone dry and the air box was clean as a whistle. macka
