The ECS inlet hose was it this one? -
ECS - 010944ECS01 - Silicone Turbo Inlet Hose
Was chatting with a local APR tuner today and running through options. He mentioned modding the air inlet duct with a dremel to open up the passenger side, where it's blocked and close the side from the engine bay. Asked him about water getting in, reckons in 5 years of doing it, they'd never seen a problem in their workshop. There does seem to be a bit of conjecture on the net about it, you can buy the duct pre-done so it can't all be bad.
He also mentioned the turbo muffler delete wasn't a measurable increase on a dyno in his experience, but seemed better noise wise and the Turbo spooling up a bit better.
Maybe time for that tune :cool:
