INJEN TECHNOLOGY - A DECADE OF INNOVATION

For over a decade Injen Technology Co. Ltd and our sister company has played a major roll in the design and development of air intake systems.  Injen Technology is based out of California in the same city and just a few miles away from the famous Pomona Winter Nationals Top Fuel Raceway.  Injen Technology's history is a classic success story of a small manufacturing company turned industry leader of aftermarket performance products.

What most people do not know is that Injen's sister company, RD Metal Works established in 1981, was actually designing and manufacturing air intake kits for leading air filter and intake manufacturers since the mid 1990's.  Absorbing the experience, design capabilities and quality standards of RD Metal Works, Injen Technology was formed.  In 1998, we embarked on a never-ending quest to brand our own name and set new standards of quality and performance while constantly striving to improve our own engineering capabilities.  Bringing together all phases of manufacturing under one roof proved to be the equation for unrivaled success.

Injen Technology has made it a point to stay at the forefront of performance technology making only the best air intake one can envision.  In 1999 Injen was faced with such a strong demand in both US and Canada that in order to meet production schedules it became essential to branch out and add a second building.

In 2003, Injen Technology launched our Super SES stainless steel cat-back exhaust systems complimenting our line of air intake systems.  Each exhaust system was equipped with the Injen signature style slanted mufflers and featured highly polished stainless steel. 

In the fall of 2005, Injen Technology announced the arrival of The SP Air Intake System.  The SP series was equipped with MR Technology launching the “World's First Tuned” air intake systems.  In the winter of 2005, “Power Flow” was introduced with MR Technology and an all new Power Box.   This was another leap forward for Injen Technology, launching the company into the largest of the automotive market segments; Truck, SUV and High Performance Automotive. The new product line was displayed for the first time at the 2005 SEMA show and won the International Product Award.  The Power Flow series has received rave reviews from both existing customers plus our newly targeted market of jobbers and warehouse distributors.

April 2008, Injen launched the companies latest product line; the Diesel Power-Flow .  Once again Injen set new industry standards by incorporating the first Power-On-Demand air intake system with Vi Technology and with a removable stainless steel Pre-Filter.  In conjunction with the launch of the diesel line, Injen also announced the Co/Branding partnership with AMSOIL, Inc. Injen and AMSOIL teamed up to incorporate an Injen/AMSOIL High Performance dry media into the new Power-Flow diesel air intake applications and the Power-Flow gas models.   Both Injen and AMSOIL will market the Power-Flow series of air intake systems.  As in the past, Injen continues to set the industry bench mark for innovation, styling and technology.

With such an enthusiastic response for our new products we anticipate solid sales growth within all market segments.  Our innovative designs, high performance standards and quality workmanship will pave the path for our continued success for years to come.  At Injen Technology we are committed to “World Class Customer Service”.

Air Intake and Induction » Mass Air Flow Sensors

What is a Mass Air Flow Sensor or MAF?

The mass air flow (MAF) sensor is part of your vehicle's electronic fuel injection system. The MAF sensor calculates the total amount of air entering the engine through the intake tract, and tells the computer how much fuel to inject for air coming through the intake. 

 

 

How does a mass air flow sensor work?

The mass air flow (MAF) sensor has two sensing wires in the housing that protrudes into the intake tube prior to the throttle body.  One wire is heated by electrical current, the other is not heated at all.  As air flows across the heated wire, it cools the wire down. When the temperature difference between the two sensing wires changes, the MAF sensor automatically increases or decreases the current to the heated wire to compensate, telling the computer how much fuel to send through the fuel injectors.

 

How much horsepower and mpg increase can I expect from an aftermarket mass air flow sensor?

Aftermarket performance mass air flow (MAF) sensors replace your OEM sensor and improve on mileage and can increase horsepower by up to 20-HP, depending on the vehicle and engine. Performance MAF sensors increase airflow and low-end torque, without robbing top-end power, and works with factory electronics.

 

What are the symptoms of a bad mass air flow (MAF) sensor?

  • The engine hesitates or drags while under load or idling.
  • During acceleration, you experience hesitation and jerking.
  • The engine coughs, sputters, or hiccups.
  • Excessively rich idling or lean idling.
  • The engine is difficult to start or crank over.
  • The engine stalls or dies shortly after starting.

 

Can you drive with a bad mass air flow sensor?

Yes and no. Yes, you can drive your vehicle with a bad mass air flow (MAF) sensor, but only to get it home or to a repair shop to fix or replace it. Ignoring this problem can lead to far more severe engine problems and damage.

 

Why would a car run better with the mass air flow sensor unplugged?

If your vehicle runs better with your MAF sensor unplugged, you likely have a shorted-out sensor. When the computer does not read a signal from your mass air flow sensor, it provides the computer with a stock signal that will allow you to drive your vehicle for a short period of time to get it fixed or replaced.
