Hello all, I would like to know where you all get your upstream 02 sensors with the heat guard for your 06 models? I know they have them at AutoZone and O'Reilly's but I am curious if anyone knows of any aftermarket ones that work just as well? I checked places like Amazon but the reviews mentioned many issues with making the car too lean or loss of power. I'm not trying take any of those risks and if I must, I will pay the $200. But I figured I'd give here a chance first. Thank you in advance for taking the time to read this.
