Yes it does stop it leaking if you do the bolt mod, I removed the SAI because the ribbed pipe that connects to it cracked and VW wanted something like £16 a section x 2 or 3 sections

I also use a CAI so didnt need to run the pipe into the Airbox
frees up loads of space in the bay, when I get round to it I'll do some pics

Bavs replaces all the standard tubing which is prone to breaking down and splitting with silicone tubing where as the link I posted removes the N249 and N112 and the hardlines are replaced with 2 sections of silicone tubing, one from the plenum to the DV and one from the plenum to the FPR
In short if it can go, on mine it goes
