Get rid of all that stock rubber piping by replacing your upper intercooler pipe with this aluminum mandrel bent peice. Made from 2.5" or 3" 6061 aluminum, this pipe reduces the number of bends and connections creating less restriction and better flow. The kit comes with a 2 peice upper pipe, 3 high temp 4-ply silicone couplers, and 6 heavy duty SS T-bolt clamps. This upper pipe is designed to be used with a mini battery kit. Depending on what BOV you are running, you may need to supply a small piece of hose for the BOV recirc tube. Coupler brand may vary. 3" kit is NOT compatible with the ETS style FMIC.
