Does anyone know whats the best location for O2 sensors on a twin turbo car? On my 06. RSI car, they're about 1 inch past turbo's. This is the 2nd. pair that has failed. (Replaced 1 1/2 yrs ago). Was told they should be at least a foot away from turbo's. AEM said too much heat can make them fail. Any help is appreciated. Other than this problem, the car runs great. Thanks.
