hallo zth,
i need help here, ive change back to std td05h turbo 4 months before,
last week go for tuning to adjust everyting,air flow,ignition timing,and boost pressure as i feel im wasting the fuel and the car...
just got my hand of the stock ori air filter box..... was looking at the filter box, noticed that there are a few small inlets where u need to insert the vacuum hoses.....
