Ford Mass Airflow Sensors
GMS is the only aftermarket company that truly calibrates each unit on a
proprietary designed computerized flow bench to guarantee performance. Changing
sampling tubes for proper calibration is guesswork at best and will cause
drivability problems and failed emission tests. The same can be said for
porting your stock mass airflow sensor or installing larger billet ends.
Furthermore, any performance gain is cancelled out after many kilometres of
driving as most factory computers “learn out” this modification.
Because the GMS mass airflow sensors are "truly calibrated" they
provide 10-15 rear wheel horsepower without drivability problems, emission test
failures, guesswork, or lost performance after kilometres of driving.
HOW IT WORKS:
Mass air induction systems measure airflow directly with an electronic
"hot-wire" type 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 method of airflow measurement reduces the
calculations required to control fuel flow and ignition spark advance. The
sensor can react fast and accurately to the sudden changes in airflow while
improving overall vehicle performance and drivability.

More power for onramp acceleration, more power for passing, more power
racing, just plain more power. GMS mass airflow sensors are exactly what you
need for your car. The mass airflow reduces the amount of time it takes for the
new computerized engines to determine changes in the air intake. The quicker and
more accurate the engine's ignition components can react to this change, the
more efficiently the engine runs, producing more horsepower. In addition, the
smooth design of the sensor's inlet tube improves airflow allowing 47% more
airflow capacity than OEM equipment. Your performance will be remarkably
improved down low where it counts and all the way through your power band. No
matter how you use car, the GMS mass airflow sensor promises to get the exact
punch you've been looking for. They install easily in 10-15 minutes using simple
hand tools. Even if you’ve never worked on your car before, you can install a
GMS mass airflow sensor. To ensure a
trouble free installation, each mass airflow sensor includes premium hardware
and detailed installation instructions.
FREQUENTLY ASKED QUESTIONS:
What is a mass airflow sensor?
The mass airflow sensor meters the CFM (Cubic Feet Per Minute) of air as
it enters the engine via the throttle body. Ford vehicles use hot wire
What's different about the GMS
mass airflow sensor and stock?
Most stock automotive mass airflow
sensors are 65-70mm in inside diameter. The GMS mass airflow sensors are
81mm-90mm, featuring 47% more airflow capacity than the stock sensor.
The advanced, active-electronic module packaged within the sensor provides
improved control of injector timing and ignition timing.
How much more horsepower will it
Typical horsepower gains are 10-15
horsepower at the rear wheels. Usually, customers exceed our claims.
Where will I notice the
Typically, from 2000 rpm throughout the entire power band.
Will it affect fuel economy?
While we do not sell our mass
airflow sensors as mileage improving devices, it typically requires less
throttle angle to achieve the same speed. Therefore, you will see an increase in
mileage if you maintain a calm driving style. However, if you drive aggressively
nothing can improve mileage.
Will it work with
Yes. The GMS mass airflow sensor
has the ability to automatically compensate and calibrate for typical
modifications. Custom calibration is required when running larger fuel
injectors with Ford mass airflow sensors.
Does the computer relearn the fuel
and timing curves cancelling out any performance gain?
No. GMS mass airflow sensors are
"truly calibrated" on our proprietary computerized flow benches and
plays no tricks on the factory ECM/PCM.
Can a GM mass airflow sensor
compensate for fuel injector size changes like the Ford sensors do?
No. Due to the inner-workings of
the GM style mass airflow sensor, they do not have the ability to compensate for
fuel injector changes like the Ford sensors can. In fact, this is another great
feature offered only by the GMS style Ford mass airflow sensor. On Ford
applications, we have the ability to calibrate the meter internally so that
simple fuel injector upgrades can be made to your engine without sacrificing
idle and drivability quality. Yet, you can gain big performance improvements by
allowing the engine to receive more fuel under heavy load conditions.
Will it work with nitrous
Yes. Nitrous-calibrated mass airflow sensors are available on a
custom order basis.
Is it easy to install?
Yes. The installation takes 10-15 minutes with simple hand tools. To
ensure an easy installation, every sensor includes detailed instructions.
When do I need cold air
Cold air inductions significantly increase airflow and can cause
tremendous turbulence in the air intake stream. When using the GMS mass
airflow sensor with any type of cold air induction, high flow induction, or high
flow air filter, your GMS mass airflow sensor must be calibrated with cold air
tuning or a check engine light can occur. Cold air tuning is
designated by a "C" as the last digit in the part number. Cold
air tuning is also available for existing GMS mass airflow sensor owners.
