Having the O2 sensor as close to the turbo as with my mufflers is not optimal for sensor life. I always suggest a heat sink for those who leave the O2 sensor in permanently, especially track cars. O2 heat sinks are not expensive and widly used in other applications. Mine has been in several years as well but the car sees no track time anymore so it is easy on the heat/sensor.
