Thanks for the reply kyle...I have a filter very similar to the one they have, what I wanred to know is how they avoid getting a CEL from their intake...Honestly there doesn't seem to be many non turbos on the forums. I'm sure someone has it but just aren't very active to reply.
From my experience air intake will have minimal gains on a naturally aspirated engine. The fact that the aftermarket intakes have such little effect on the T5 I wouldn't bother. Use the money towards something else.
