TGK Motorsport Coolant Tank AN Line Kit - C7/7.5 S6/S7

Engine dress up and function

Awesome product to replace the brittle and very easily breakable return lines to the reservoir. 10/10 would install again

You should have these.

If you plan on doing your own maintenance, especially your plugs or coils then you might as well install these lines while you're at it. Don't add much time to the job the first time doing it, and will help give peace of mind and ease of completeion everytime after after. Definitely worth it.

TGK does it again!

Stoked on the new TGK coolant line set-up. Perfect fit and function. Way cleaner than the stock coolant lines.
