Features
- INTRODUCTION: Mass Air Flow Sensor (MAF) determines the mass of air entering a vehicle's fuel injection engine, and passes that data to the engine control unit. This balances the air and fuel ratio to promote successful combustion. When the MAF Sensors goes bad, it can lead to various symptoms, ranging from an illuminated check engine light to rough running and misfiring.

⭐️⭐️⭐️⭐️⭐️ Saved My Regal GS – Runs Like a Champ Again I bought this BDFHYK MAF sensor for my 2001 Buick Regal GS (supercharged 3.8L), and I couldn’t be happier. My Regal was running rough—poor acceleration, weird idle, and that lovely check engine light. Swapped this sensor in and it was like night and day. Install took less than 10 minutes with basic tools. Unplugged the old one, popped this in, reset the codes, and the car started running smooth immediately. Throttle response came back, fuel mileage improved a bit, and the idle finally leveled out. Fit perfectly, no weird codes or issues, and way cheaper than the parts store or dealership. Been running it a few weeks now with no hiccups. If you’ve got a 3.8L GM like the Regal GS, this one’s a solid replacement that won’t break the bank. Definitely recommend.

My 2004 Buick LeSabre suddenly began to have intermittent misses at speed and intermittent stalls when idling. It didn't actually throw a code, but when I plugged in my OBD II fob and looked at the readout, it did say a P0102 code was "pending". (P0102 on my car is "Mass Air Flow (MAF) Circuit Low".) I purchased the BDFHYK Mass Air Flow Sensor Meter MAF 213-3428, after checking other auto parts sites and finding MAF sensors priced at a minimum of $60 - and genuine GM was $180! This MAF sensor was highly rated and about $24, so I gave it a shot. After a thorough test drive, I determined the problem was fixed. The car runs great again. This is a brand new installation, so I will revisit this review should it fail prematurely.

Upgraded all of my sensors and tubes to my 04 Lesabre and put this MAF sensor in a few months ago. Past week my car started throwing a 0171 lean bank 1 code and I could not figure it out for the life of me. Changed my O2 sensors and did a smoke test of the engine and kept getting the stored code. Then something told me to reinstall my old MAF sensor and what do you know, no more 0171 code for weeks. So something with this new maf sensor fell out of spec and started confusing my ECM. Buyers beware, your care may work fine with it or if you use it on older cars it may fall out of spec for you.

Works as advertised. Product looks good and installed painlessly. Checking now if it will change my mileage. It's great that they provided a tool that fits the special screws to install it.
