Review on 🚗 Chevy, Cadillac, GMC Compatible Mass Air Flow Sensor - Impala, Monte Carlo, S10, Blazer, Malibu, Astro, Grand Prix, Intrigue, Cutlass and More - Replaces 2133458, 25008302, AF1004 by Dre Fowler

Judging by the reviews this is more of a temporary fix until you get a better part. I actually bought mine on 3/2/2020, i.e. a year ago, just as a backup in case my AC Delco brand air mass sensor fails. I finally installed it today on my '94 Grand Prix and immediately noticed a difference in performance as soon as I got going. Also, my car runs pretty smoothly. In other words, so far so good. I still intend to buy another MAF in case that one fails. But it exceeds my expectations given its cost compared to more expensive MAFs.
