I own a 2004 BEW Jetta and a 2011 TDI Jetta with 6spd MT. I love it. Mine has been "Updated" with Rawtek exhaust and Malone stage 2. I have gave a few Hemi Chargers on the highway a good run. Leave them scratching their heads. Passengers are always impressed with the power/torque. The MK6 TDIs...
The previous owner mentioned upgrading the cold air intake for increased performance and MPG. Currently has Malone Stage 2, Rawtek straight piped, deletes etc... I know on the MK4s it's not recommended by most. I'm not sure on MK6
I'm going with Koni Special Actives. They don't fit the beam axle on our 2011s. There is a bushing kit available to make them fit. Which if your comfortable with that, then that opens up a lot of options.
My Jetta has 169K on 2011 TDI Jetta . I'm going to replace Shocks/Struts. My main goal is comfort. If I can get some performance without sacrificing comfort that would be good too. Any recommendations? I'm keeping stock height and 17" tires
