Over 50 years have passed since JET performance Products started life as an engine building and carburetor shop. At the time, the company was focused on drag racing applications providing race engines and carburetors to local Southern California drag racers. The company also ran many of its own cars in both NHRA and IHRA, which resulted in setting national records in three different classes. Over the next several years the company continued to grow and it became apparent that Carburetor tuning was going to be the companies future as they had become the “go to guys” for carburetors and carburetor tuning. At that time the company was renamed Mike Jones Carburetion after one of the founders and over the next 17 years the company developed and tuned carburetors for some of the top names in Drag racing, NASCAR and Off Road racing in addition to building some of the fastest and most reliable street carburetors in the business. By this time, these carburetors were being shipped all over the United States and Canada.
In 1985 Mike Jones sold the company to the current owner Bryant Seller. An Auto Mechanic, Tuner and Drag racer, the company was a great starting place for Seller to develop new products and grow the tuning business. In the mid 1980’s the automotive world was entering into a new era with the introduction of computer controls and fuel injection in most new vehicles. The way to tune vehicles was about to change forever, no more recurving distributors and re-jettting carburetors, electronics was going to take over the automobile industry. Initially these changes looked like they would kill the performance industry, but change brings innovation and new opportunities. Seeing the opportunity and the challenges in these changes Seller, along with a friend that was an electronics wizard, set out to reverse engineer these new computer controlled cars and trucks to see what could be done to improve the performance. After thousands of hours of research and development the first JET Performance Chip was released for General Motors applications. The Company was renamed JET Performance Products and on the way to becoming the leader in computer controlled tuning technology.
Over the past few years, JET has released over a 100 new applications and a complete new product line, the JET Xcelerator. JET Engineers and team continue to bring new and innovative products to the market and develop products that will enhance your automotive driving experience. Accesspeed is proud to offer JET Performance products to our customers. With our lowest price match guarantee, you will always find the best combination of price and selection at Accesspeed.

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.
