02 Sensor Question













Am I able to use to same 02 sensor to replace all the old sensors or are the sensors different in each location? I bought one of these already - http://www.amazon.com/gp/product/B000BZI4JS/ref=oss_product

Thanks!

That is the upstream sensor of which you will need 2. The bosch downstream sensor is part # 15718. 2 are needed as well. The difference between the 2 part # from what I can tell is the length of the connector pigtails as the rear ones have to be longer as they are farther away from the main harness.
