Euro Sport Intake
Our hosts had been waiting to try their Cool-Flo Race air-intake on a TDI and this would be the opportunity. With a minor modification, they planned to use an existing Mk5/A3/CC 2.0TSI intake that comprises a metal intake tube (available in black/wrinkle or chrome/clear powdercoat), ITG cone filter and two silicone connectors. The only difference between our diesel and most gasoline models is an additional vacuum hose on the TDI, but a simple nozzle would accommodate that. So we went ahead with the installation you can read here or online.
With Euro Sport's CAI installed, we definitely have more induction noise, and a sporty turbo sound. But would it make a difference on the dyno? With the temp up to 83?F, the three runs produced 132, 133 and 134whp. With the correction factors, this did mean we'd gained 2-3hp in the mid-range with our intake and exhaust. While it's negligible, we are finally moving in the right direction. The next step will be some performance software to see if we can finally get this 2.0 four-cylinder turbo-diesel cooking. Stay tuned for the next update.
