Review on 🔥 Black GM Genuine Parts 213-819 Heated Oxygen Sensor for Enhanced Engine Performance by Dustin Ramsey

I would suggest calling the dealer with your Vin to check which of the three O2 sensors will fit or look at the connectors you have. The ACDelco website gave me the wrong information but the seller allowed the return with no problem and I reordered the correct ones from them. Bank 1, the driver's front, is very difficult to swap out on a 4WD car because the drive shaft is in a location where the other three can be easily swapped out. The truck runs much better, responds better, pedals less and accelerates better, and my gas mileage is down a bit. It's been 17mpg most years, but the last pair has dropped to 12. After the exchange, it went up to 15, hoping it will go up a bit more. I chose OEM because it is a quality product and after reading many reviews I decided it wasn't worth saving $10 or $15 per sensor when using other brands. That matches my 2001 Silverado with 206,000 miles.
