Custom Piping Setup

Reworked my crash bar for an OTS intercooler kit for my ‘13 speed 3 and needed a 45 degree to turndown to the piping from the core. These worked flawlessly after some trimming down! Would recommend to anyone. High quality coupler for a great price.

Coupler replacement

This works great if you get a Cobb front mount intercooler for 15+ STI and you have the MAP intake
