Performance You can Feel
The extra power you need when you need it: on the ramp acceleration, on demand passing, towing, through the hills or wherever. Granatelli Motor Sports performance mass airflow sensors reduce engine load and improve efficiency. This occurs by providing quicker and more accurate calibrations to changes in engine intake airflow, fuel and spark timing. In addition, the smooth design of our sensor's inlet tube improves airlfow capacity over OEM equipment by and 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. Ally you need are basic hand tools and 10 minutes of your time. Just follow the included step-by-step instructions and you'll enjoy 10-23 rear wheel horsepower in no time. Now that's performance, quick and easy!

How They Work
Mass air induction systems measure airflow systems measure airflow with an electronic "hot-wire" type mass airlfow 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 airlfow measurement reduces the calculations required to control fuel and ignition spark advance. Mass airlfow 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.
