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 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.
