Ever since I had the car it had an unusual turbo whistle. Whilst doing an oil change I spotted one of the intercooler hoses had been jammed in (hard) at a strange angle so it wasn't sealing. On closer inspection the retaining lugs had been broken off and some gorilla had jammed it in place. Knowing that OEM hoses are expensive I started searching ebay and was astonished by the low price.
The hose has been fitted for 2 weeks and I've driven around 600 miles with it. The whistle is gone, the car responds even better to the throttle and because all the air from the turbo now goes into the engine, fuel economy is up too. I'll have saved the price of this hose in fuel savings quite soon!
After 2 weeks I can't comment on whether it is built to last, but the lugs engage the clips on adjacent hose/intercooler as they should and the rubber seals keep the air in the system which is all I need from it.
