They are the stock IC Pipe connections but they have all new gasket seals, have been sprayed with hairspray (great for sealing air lines) and the IC lines with clamps are checked religiously. I'm telling you brother, as far as I know this is a problem without a solution in sight.
I'm betting that those connections with the clips and o-rings are the culprit. maybe not all, bit one is probably fudged. what makes me say it, is I had a leak like that, but even after new seals it was the same, so I just assumed that was normal to have laggy response ect. until my pcv plugged and I got a shit load of oil and crap into my charge piping, and it started seeping from those spots. I'd remove and clean them (and yes hair spray, which works much better on the hoses with traditional clamps, btw) and it would be good for a lil while, then they would randomly leak. I'd have to redo everything again, clean/spray ect to get back to normal. only way I fixed it was to go aftermarket connectors with the silicone hoses, cuz those adapters are bigger then the stock, I had to tap mine in with my dead blow hammer. so I'm thinking the stock will get cockeyed in there and the seals won't seal. cuz my stocks would wiggle slightly when clips were in too
