aFe Cold Air Intake

Get up to 19 hp and 64 lbs of torque with a new air intake system!

The aFe Stage 1 air intake system can get you gains of up to 19hp and 64lbs. of torque and has an outflow that blew the competition away with a 38 percent raise above stock. This system includes a Pro-guard performance air filter that greatly improves air flow for the best performance possible. The completely washable and re-useable filter is made out of 100 percent polyurethane. The aFe Stage 1 air intake system is meant to be a replacement for your trucks stock intake box and in its place offer a one-piece intake system that will bear obvious enhancements in power, airflow and torque.

What comes with the aFe Stage 1 air intake system?

This system comes uses a stock intake tube and comes with a one-piece 16 gauge heat shield. It also includes a giant high-flow reusable filter with conical air filters and a three angle adapter to minimize aerodynamic loss. The hardware that comes with the system is high quality hardware such as head bolts and brass inserts.

How does an air intake system work?

Air comes in through the air intake. The intake consists of  long plastic tubing going into the air filter housing. The air coming in is most beneficial if in a steady stream, thus the use of a long tube.  After the air filter housing the air goes into the air filter and then into the air flow meter. Two types of ARM’s are present in a diesel engine. A Vane and Hot Wire.  the Vane ARM uses a flap that gets pushed back allowing more air to pass and the Hot Wire releases voltage as air heats. After the ARM air flows to the throttle chamber. This chamber controls the airflow to the engine.  When the throttle chamber is shut, the engine idles. Inside this is a bypass chamber that lets some air go past the throttle plate and into the engine. Adjusting the amounts of air that is allowed to pass determines the idle speed of the engine. The throttle position sensor then sends a signal to the trucks computer that determines if the car is idling, midrange cruising, or open throttle. Afterwards, it goes into the intake manifold and into the cylinders. The last part of this process includes the air flowing to the cold start valve which expands as it gets hot. In cold conditions, a large amount of air goes to the throttle plate which produces an increase in idle speed. As it gets warmer, the bypass closes and lowers the idle speed and the engine attains a normal temperature for optimal operation.
