The air that goes inside the engine must be measured to come up with the right air-fuel mixture. This is job is best handled by an air flow meter. This meter sends signals to the engine computer, basically relaying the amount or bulk of air that enters the system. Through this information, the computer is able to adjust and control the drops of fuel that will be injected for combustion and power generation. Unfortunately, this meter can get clogged up with dirt and eventually fail. With a faulty meter, you may notice excessive black smoke coming out of your vehicle and decreased gas mileage. Your vehicle’s performance will also suffer with reduced drivability, loss of power, and running difficulties. A warning light may come on when the meter fails. A diagnostic tool or machine can be used to figure out the problem. Once you’ve confirmed that this part is the trouble-maker, you’ll have to replace this right away.
New vs. remanufactured
Not all airflow meters sold in the market come with 100% brand new components. Some of them are remanufactured. Although remanufactured sensors may use restored components or recycled parts, these are tested to make sure that they function properly. They also come at a much lower price compared to brand-new meters. But, if you want uncompromised quality and performance, you may be more comfortable buying a completely new air flow meter. Look for a meter that matches the specs of your vehicles and one that meets the industry standards.
Stock replacement vs. performance upgrades
Some airflow meters are simply designed as stock replacements. These are designed to have OE-comparable quality and design. If you want better performance and special features, then you should be looking for high-performance airflow meters. These meters are a good option for racing vehicles and high-performance applications. These come with added features and may function better than the stock air flow meter.
Direct fit vs. universal fit
Some airflow meters are designed as a direct fit to specific vehicles. These sensors match the specs of particular vehicles and can be installed more easily. Meanwhile, universal airflow meters can be installed on different vehicles or numerous models. Some of them, however, may require minor modifications. When shopping for a new air flow meter, take note of some product details such as the OE number, terminal, material, color/finish, and blade type to see if it matches the OE specs.
