I'm guessing at this but if someone did have an issue with the sensors in the kit , probably the dealership would be able to get them directly from GM with the part number, even though they aren't an off the shelf part, but they would have to order it specially. I also would like to put a theory out thier to any one willing to research this, but it could be possible that Saab turbo models 2.0,2.2,2.4 vvtechs might use those sensors , but i'm not definite,but maybe someone familiar with these things could find out.
