RS6 – Replacing Vacuum

Turbocharged cars like the RS6 require many attributes of the to be performing perfectly to maintain performance. One of the cheapest fixes and to diagnose, is vacuum and boost Many of the emissions and accessories on are controlled from vacuum in the intake system of the engine.

related to performance and accessories, are all together into the same One leak in any rubber hose can to degraded performance from a engine.

I was inspecting the condition of my stock vacuum lines in the RS6, and a few of fell apart in my hands. I that instead of replacing I would replace them all quality silicon hoses. I 15′ feet of blue hose from ECS tuning, is my usual preferred vendor for performance parts.

I had to the silicon hose around the and back to the intake port to for enough distance to install the

If you do not have a boost gauge, you will not have to worry this problem.

I used zip ties to tighten the ends of the lines. Pull the zip ties and then cut them off with a cutter. Once you are complete changing all of the lines, reinspect all of the to make sure you didn’t installing a zip tie.

When complete, you should something that looks the following.
