Cobb 04-07 Subaru STI / 02-07 WRX / 04-08 FXT 3-Port Boost

The COBB Tuning 3-Port BCS features 1/8" low-profile barb fittings to keep the unit compact, and are nickel coated for corrosion resistance. Optional 1/4" nickel plated fittings are also available separately. Viton spools and seals are used throughout for long life and lubricated with Dow Corning silicone grease. The manual override port is sealed with an O-ring, the wiring harness is sealed to the casing using a waterproof grommet and the solenoid wires are ultrasonically welded to the coil, making the device waterproof and safe to wash.
