IE Aluminum Charge Pipe Kit For Audi B9 S4, S5, SQ5, & C8 A6, A7

Hard install but worth it

Amazing throttle response and certainly enhances the performance paired with an intercooler and cold air intake along with a tune. Easier to remove the whole front and let it hang down to get access to the hot side. Otherwise there is no space especially if the intercooler is already installed.

Major upgrade, tough install

I went with the IE Charge Pipes along with the Intercooler upgrade as well and am glad I did both; you can really notice a solid increase in airflow going from stock, and if you're going to do the FDS intercooler and have the will/patience/tools, these pipes are worth throwing on at the same time. The parts fit well and are clearly high quality, but be ready for a challenging install. I had a friend who is a senior mechanic do them for me and he said the passenger side pipe is a serious job, it took him a while to figure it out and you have to move other things around in the engine bay that are not necessarily closely described in the installation instructions. This was for my B9.5 generation S4. Overall, totally worth it, just be prepared.

"No More Stuffy (NOSE!)"

So far, I really haven't ample time to evaluate!
