Your engine needs a mixture of fuel and oxygen to produce power. The fuel injectors do exactly what their name suggests: they supply the engine with a precise amount of fuel. That fuel combines with the air delivered by your intake system. A spark plug ignites the volatile gas, creating a small explosion that forces the piston to turn the crankshaft downward. That power of the piston produces horsepower.

Maintaining a healthy and accurate air-fuel ratio is critical to engine performance. In fact, your engine needs 15 times more air than fuel to burn efficiently. That’s why cold air intake systems can have such a potent impact on the health and performance of your vehicle.
