Granatelli Mass Airflow Sensor: Granatelli Motor Sports performance mass airflow sensors reduce engine load and improve efficiency. This occurs by providing quicker and more accurate calibration to changes in engine intake airflow, fuel and spark timing. In addition, the smooth design of our sensor’s inlet tube improves airflow capacity over OEM equipment by an industry leading 47%. The added performance is chassis dyno proven from 2000 rpm to the red line. Most importantly, the performance can be felt where it counts, in the seat of your pants. Granatelli Motor Sports performance mass airflow sensors are ideal for adding extra performance with none of the hassles. All you need are basic hand tools and about 10 minutes of your time. Just follow the included step-by-step instructions and you’ll be enjoying an extra 10-23 rear wheel horsepower in no time. Now that’s performance, quick and easy!

How They Work: Mass air induction systems measure airflow with an electronic “hot-wire” type mass airflow sensor. The sensing element in the air intake provides an output voltage reading that is directly proportional to the amount of air that is entering the engine. This airflow measurement reduces the calculations required to control fuel and ignition spark advance. Mass airflow sensors can react quickly and accurately to sudden changes in airflow while improving overall vehicle performance and drivability.

Calibrated for Optimum Performance: Granatelli Motor Sports spends hundreds of hours testing and calibrating to optimize performance for your specific application. Each application is calibrated on our proprietary computerized flow bench. Then, each application is dyno tested and driven under a variety of real world tests using sophisticated air/fuel ratio monitors, exhaust gas temperature gauges and data logging computers. The result is optimum performance for YOUR specific application.
