I had to buy OEM to fix misfire, p0160, CL error.

Had to send back and buy OEM. They might work better in other cars, but even though the installers said they would fit my car, they didn't do the job. A few days later I went back to my mechanic with persistent misfires, p0160s and closed loop errors and asked him "what do we do now?" He said to get rid of cheap Chinese junk and get good Chinese replacement parts (!) deploy. I put in some Denso sensors and the problems went away immediately. I've made a lot of profits on the parts I bought from Revain, but sometimes the cheap stuff just doesn't do the trick.

Pros
