Ford Mass Airflow Sensors

UNIQUE DESIGN:
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.

SYSTEM FEATURES:

• Engineered specifically for popular electronically fuel injected 1988-2002 Ford V-8 gasoline powered car

• "Plug and Play" easy installation in 10-15 minutes

• Works with factory and aftermarket electronics, programmers, modules, air filters, cold air intake systems, throttle bodies, ignition systems, headers, cat-back exhaust systems, pulleys, roller high ratio roller rocker arms, superchargers, turbochargers, nitrous, radical cams and heads, and larger displacement engines.  Custom calibrations will be required for larger fuel injectors

• Dyno proven to add 10-15 rear wheel horsepower

• Flow bench tested to provide 47% more air than stock mass airflow sensors

• Reduces 1/4 mile times by 0.1-0.2 seconds

• Improves power and throttle response from 2000 RPM on up

• Rugged, OEM quality fit and finish

• Will not void factory warranty

PERFORMANCE GAINS:
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 style sensors.

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 provide?
Typical horsepower gains are 10-15 horsepower at the rear wheels.  Usually, customers exceed our claims.

Where will I notice the extra power?
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 aftermarket modifications?
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 oxide?
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 tuning?
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.
