If your check engine light is on or your truck's running rough, a faulty mass air flow sensor might be the culprit. This replacement MAF sensor is designed to fit a ton of Chevy, GMC, and Cadillac vehicles with 5.7L V8 engines from the mid-90s to early 2000s. That includes models like the Chevy Corvette (94-95), Express Van (96-02), Suburban (96-99), Tahoe, GMC Savana, Yukon, Cadillac Escalade (99-00), and many more. It replaces OEM part numbers like 2133457, 19208521, and several others – check your old sensor or vehicle manual to be sure. The MAF sensor measures the air entering your engine to help optimize fuel mixture, so a good one is key for performance and fuel efficiency. Installation is usually straightforward, but always double-check compatibility for your specific year, make, and model before ordering. A reliable aftermarket solution to get your ride running smoothly again.
