Using this GFB wastegate actuator is easy. First, make sure your car engine is off and cool. Locate the factory turbo's actuator and carefully remove it. Then, simply bolt on the GFB WGA part #7303 in its place. Remember, a tune is required after installation. When it comes to maintenance, check the actuator regularly for any signs of wear or damage. Keep it clean to ensure optimal performance. Also, if you notice any unusual noises or a drop in performance, it's a good idea to have it inspected by a professional.
