Vacume Lines Help
I was under the hood the other day and i noticed that the fiber braided vac lines on top of my throttle body (2.8) are cracked up and falling apart. Is this bad for the engine? Does it rob power in anyway? The lines arent falling off but i can tell that if i muscle them they will crack for sure.
Replace? Silicon tubes?

RE: Vacuum Lines Help
I've noticed that on my oldcar. The factory lines are verygood quality and even if the outer braiding in wasted, the lines are probably fine. i had a 1996 2.8 a4 and i replaced all the lines i could hoping to solve a problem and it did not. This was at 198,000 miles. all the lines wereholding up. Unless you arehaving problems or codes i would just leave it. But Preventive maintenance on an Audi great practice, especially things you can do your self.

Well cincy i have seen 3.0 A4's with all that vac line replaced with silicon tube after a supercharger install so it looks under the hood. I liked the way it looked very much.
So bad vac lines can rob the 1.8T of power (boost)...can it do the same for a 2.8?

Any holes in a vac line are bad for the car. Just get some rubber lines from your local parts store, their cheap and easy to replace. Silicone won't get you anything but a look, and it's really expensive.

And yes, they do need to be there. IIRC, they are for the tuning flaps in the intake manifold on a 2.8.
