Don’t buy
Junk doesn’t work with D13 engines, after installing and doing data relearn and a forced regen got a new check engine code (u008088 ) no communication from outlet nox sensor spend the money and buy OEM.

DON’T BUY THIS! VERY UNHAPPY!
This product obviously wasn’t any good. A week after it was installed the engine light went back on. After being in the dealer for a week they found out that the sensor was bad and had shorted out and needed replacing. Lost a weeks worth of pay.VERY UNHAPPY!!!
