ACDelco GM Original Equipment 213-1545 Manifold Absolute Pressure (MAP) Sensor

Works good,box says genuine gm but under part says made in China,I never expected that but it works so that's what matters,I guess all gm parts are china now days.

Easy to install. Fits my 95 Silverado 454 TBI. Product described as ACDelco but don't see any markings that say ACDelco I don't know if that's normal hopefully it wasn't just a cheap knockoff and that's the name they're using. Working great so far compared to AutoZone and O'Reilly's parts. And I'm definitely an AutoZone person but went through three map sensors and it wasn't working to the point where I ended up thinking of something else but it still was the map sensor got one from O'Reilly's worked all right but just said forget it and got ACDelco works great.

Not A real GM manufacturer part it’s china made but works

nothing

Worked like a charm.

Easy to install, only wish the seal was provided being my old one was worn out!

I had bought one on eBay and it failed within a few months. They advertise as GM parts but we’re not. Decided to take a chance with this one and the car is working now. Will only buy OEM now and not aftermarket, have had 3 different parts being aftermarket that failed.UPDATE: Have still had problems with the car stalling today the service engine light went on so was able to use the diagnostic tester and it shows the MAP nearly putting out voltage. Car was chugging when I would hit 61mph and not wanting to start when warmed up and stalling out when stopped. I even asked the seller and had GM confirm that it was an authentic part and they said it was and that they had several places in China tha make these parts. Obviously they are no longer reliable for parts. Have to contact seller to see if they can refund me or not. Doubt I even drove the car 200 miles since installed because of being afraid to drive it. Only would go 3 miles to town for groceries and a doctor appointment. Really bummed out because went thru bad mass air flow sensors (bought 2 on eBay, finally giving up and bought one from Autozone) and have been without a reliable running car since last April when I put the first MAS and MAP in from the same EBay seller. Learned my lesson to stay away from AC delco now.

Works good

Works as it should.

GM quality, good price, quickly shipped. Can't say anything better than that.

I purchased this ACDelco MAP sensor to replace the original on my 1984 Corvette C4. Installation was straightforward, and at first, it seemed to do the trick - my engine idled smoothly and the check engine light went off. However, my satisfaction was short-lived. After only a few months, the MAP sensor started acting up again. The engine would randomly stumble and misfire, with the check engine light coming back on intermittently. I tried cleaning the electrical connections and even replaced some vacuum lines, but the issues persisted. It became clear that the "ACDelco" unit had failed prematurely. Ended up buying an actual OEM delco unit off eBay and has been working okay so far.
