Peace, mercy, and blessings of God be upon you. I have a new exhaust sensor connector, only one available. It's a replacement for the catalytic converter or the leaded exhaust. The exhaust sensor or oxygen sensor piece with a mini-catalytic converter is made of steel. It cancels the engine light and improves computer readings. This is after I installed it on an Elantra 2020, 2000cc engine, and the engine light turned off. I have one used for a week, selling for 50.
