CRC Mass Air Flow Cleaner was the first item on the market specifically designed to clean the mass air flow (MAF) sensor in your car, which can increase horsepower, enhance fuel efficiency, and improve engine performance. Safe on all car parts and plastic, it dries instantly, removes buildup and debris, and leaves behind no residue or chemical buildup.

CRC continues to deliver game changing products consumers trust most in the automotive parts cleaner category.
Here are a few of the ways you can improve the performance of your car with CRC MAF Cleaner.
A clean mass air flow sensor helps increase a vehicle’s horsepower and torque. Removing debris from the MAF sensor will optimize its ability to measure engine airflow accurately and effectively. CRC Mass Air Flow Sensor Cleaner has been thoroughly proven through dyno-testing to provide the best possible results.
A vehicle's fuel efficiency is measured in miles per gallon (MPG), reflecting the number of miles a vehicle can travel on one gallon of gas. A clean mass air flow sensor will more accurately measure incoming airflow, increasing engine efficiency which results in improved MPG.
The right air-to-fuel ratio enables fuel to burn at maximum efficiency. Keeping the mass air flow sensor clean as it measures airflow improves the air-to-fuel ratio. This will help your engine measure the airflow more accurately, delivering improved performance.
It is recommended to clean your mass air flow sensor every time you change your engine air filter, or at least once per year.
The mass air flow sensor is a key part of your vehicle's electronic fuel injection system. It measures the amount of air entering the engine, as well as the engine airflow. Most modern cars use a hot-wire type of air flow sensor.
A dirty MAF sensor can cause inaccuracies in the measurement of airflow to the engine. This can lead to several potential problems, including:
CRC Mass Air Flow Sensor Cleaner is available now for those who demand performance, desire maximum fuel economy, or take pride in their vehicle. As the first mass airflow sensor cleaner specifically designed to tackle this chore, CRC can be trusted to improve your experience with your vehicle. Use it at least once a year to improve the driving experience for yourself or for someone you love!
