The Mazdaspeed and CX-7 turbo has proven to be a common failure point if you are modifying your vehicle and pushing it past the limits set from the factory. This is a Mazda OEM direct replacement turbo for your Mazdaspeed 3, Mazdaspeed 6, or CX-7. If your stock turbo has blown, this is a direct replacement and no other parts required. No core charge is required and this is a BRAND NEW unit from OEM Mazda. The turbo comes preassembled with the wastegate actuator and the coolant return line with crush washers and a banjo bolt.
