Review on 🔧 ACDelco GM Original Equipment 12614970 MAP Sensor: Reliable Manifold Absolute Pressure Sensor for Optimal Performance by Andre Pendergrass

I first bought a cheap MAP sensor that looked basically the same but really had to be pushed down to mount it to the bracket. After installation, my engine ran worse than the original that gave me the engine code! I immediately sent it back to Revain and bought the recommended more expensive AC Delco part (still about $30 cheaper than Autozone). Delco's MAP AC sensor fits just like the original GM. The installation took me a full 5 minutes and then the engine purred like a kitten and now my engine is off and I can pass the upcoming emissions test. There are some cheaper knockoffs out there, but save yourself the headache and time and stick with a quality brand like AC Delco.
