The Autohex Cold Start Wastegate Rattle Fix provides users with the ability to effectively prevent the wastegate from rattling during the initial cold start, particularly when the catalyst is heating up. By addressing this common issue, the fix significantly reduces the noise and vibration typically associated with wastegate rattling during engine startup. As a result, it creates a much quieter, smoother, and more comfortable cold start experience, enhancing overall vehicle refinement and driver comfort. This adjustment is especially beneficial for those seeking a more refined engine sound and a less intrusive startup noise, making your vehicle feel more premium right from the moment you turn the key.
