You had a bad experience with a sh*t intake, stop putting other people off! LOL. Yes they are noisy, its an unrestrictive intake with an open cone, of course you'll hear the turbo when it spools up, which on a K03 is pretty much all the time as its such a responsive turbo
The Revo intake is regarded as the best out there, both in terms of MAF scaling and performance. From memory TSR and LVS were running offers on the powdercoat REVO, so worth contacting them
