The cost of this part was a major factor since the original part was well over $300. Even though this part was way less expensive, it was recognized by the car which got rid of the check engine light. It even had anti seize compound on the threads. Very satisfied!

Fixed the engine light
I know many people worry about a an off brand part not working for the engine light but this did and it was literally $100 cheaper. This part was a true blessing from God but I couldnt afford the other part. Did the job well! I recommend to everyone!
