⭐⭐⭐⭐⭐ James Carter - Auto Repair Shop Owner
"I've installed over a dozen AFH45M-46 MAF sensors in Nissan Sentras and D21 pickups, and every one has performed flawlessly. The pre-drilled mounting holes make installation a breeze—no need to realign or modify anything. It reads airflow accurately right out of the box, and customers report smoother idle and better fuel economy. For a replacement sensor, this is as close to OEM as it gets."Purchase Date: February 2025 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Linda Perez - Fleet Maintenance Supervisor
"We use these sensors across our fleet of Nissan D21 work trucks, and the durability under heavy-duty conditions is impressive. Even with constant stop-and-go driving and exposure to dust and moisture, the AFH45M-46 holds up. We’ve had zero failures in the past six months, and the 12-month warranty gives us peace of mind. The standardized connector also means our techs aren’t wasting time adapting wiring."Purchase Date: November 2024 | Usage Period: 7 months
⭐⭐⭐⭐☆ David Kim - Car Hobbyist
"Replaced the old MAF on my 1997 D21 with the AFH45M-46, and the difference was noticeable immediately—no more hesitation during acceleration. The plastic housing feels solid, and the textured surface seems to help with heat dispersion. Only reason I’m not giving five stars is because I wish the packaging included a bit more guidance on compatibility verification. But once installed, it worked perfectly."Purchase Date: April 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Amina Johnson - Nissan Sentra Owner
"My mechanic recommended this sensor after my check engine light kept coming on. Since installation, my fuel efficiency has improved by about 8%, and the engine runs so much smoother. I appreciate that it’s certified to OEM standards—gives me confidence it wasn’t just a cheap aftermarket part. For a component most people never see, it makes a big difference under the hood."Purchase Date: January 2025 | Usage Period: 4 months
⭐⭐⭐⭐⭐ Marcus Reed - Automotive Tuner
"I used the Advanced Model of the AFH45M-46 on a turbocharged 2.4L D21 build, and the 300 g/s airflow range and 150 ms response time handled the increased intake load without issue. It integrates seamlessly with the ECU and holds calibration well, even under aggressive throttle cycling. For tuners looking for a reliable, drop-in MAF solution for Nissans, this is now my go-to recommendation."Purchase Date: March 2025 | Usage Period: 2 months
