The Gumout Professional Formula MAF Sensor Cleaner is excellent for keeping your mass air flow sensor clean and performing well. It sprays evenly, evaporates quickly, and doesn’t leave any residue. Using it helps improve engine performance and fuel efficiency by removing dirt and grime buildup. The 11 oz can lasts through multiple cleanings, making it a good value. Overall, a must-have for anyone maintaining their vehicle’s air intake system.

I trust the brand, been using Gumout products for decades (that's a long time). Trust me, it gets the job does, Proven formula that does not fail, no disappointments here.

This MAF sensor cleaner works great and does exactly what it’s supposed to do. It was easy to use, dries quickly, and helped improve my car’s performance after cleaning the sensor. The engine feels smoother, and throttle response improved. The spray is strong but safe for delicate components, and the can lasts for multiple uses. It’s a simple and effective product for regular maintenance. Great quality and very reliable. I would definitely buy it again.

The only thing that cleans MAF sensors correctly

Bueno

Funciona de maravilla. Un excelente producto. Que. Evita. Daños mayores a tu vehículo. Recomiendo. Lo tengan. Siempre

This cleaner did leave a residue free clean on my mass airflow sensor for my 2020 Nissan Versa that was throwing a MAF code. Unfortunately it did not clear the code and my car still will not work properly. It worked once and then any time after my car still has acceleration issues. I will most likely replace the MAF. Its a huge can so I will be saving it for future use, the spray nozzle made it super easy to get in all of the tight spots, it dried super fast, and it wasn't foamy or too liquidy.
