Review on KAX 250 24462 Equipment Replacement Downstream by Brennan Buckley

Works great for Hyundai Santa Fe 2009 2.7L. It works as a replacement for the downstream oxygen sensor on bank 1 or 2. After getting error code 430 (catalytic converter for bank 2 at the front of the car) I swapped the upstream (my other order) and downstream (this one) oxygen sensors on bank 2 , as well as 3 spark plugs (the front ones are bank 2 which are easy to replace) now the error code is gone and my car runs faster and stronger with less gas mileage! I am planning to replace the other two oxygen sensors for bank 1 (rear of the engine) and the other 3 spark plugs.
