The Tial Q is a superior blowoff valve to many on the market and features a large discharge area to quickly clear out pressure developed when you let off the throttle in a turbo car. CP-E has created a flange that is designed to interface with the Tial valve and bolt directly onto your Mazdaspeed 3 or 6. CNC machined from billet aluminum for strength and an awesome, clean look in your engine bay. In addition, they have created a recirculation hose unlike any other with unbelieveable strength for how flexible the hosing is. This IS the nicest recirculation hose money can possibly buy. This is the FLANGE and RECIRC HOSE ONLY but is also available without the recirculation hose or in a full kit with the blowoff valve.
