Okay so I'm wondering if these external kits are available, I'm pretty sure my intake will need it... I looked in there the other day and didn't see the little red thingy... also curious about the hissing noise, where does the hissing noise come from? Mine sounds like it's around the intake and only does it under boost pressure... turbo was replaced a few weeks ago and developed a boost leak and throws a p2261 code.
