Does Sea Foam harm oxygen sensors or any others sensors? [SOLVED]

Thanks for the question, Chris. No, when used as directed, Sea Foam products do not harm oxygen sensors or any other sensors. When applying Sea Foam Spray, just make sure you apply it downstream of the Mass Air Flow sensor (MAF sensor). Most MAF sensors are a safe distance upstream of the throttle plate anyway. Hope that helps and let me know if you have any other questions!
