Air Induction

Silicone hoses are now becoming a popular choice for air induction pipes as they are designed to handle the heat and pressure or vacumm of modern turbocharged engines. Some are made to replace the factory standard piping and are sized and shaped accordingly to make for an easy replacement.

For modified or aftermarket induction systems there is a large range of options available. Just like a regular plumbing supply, you can get silicone hoses in a range of shapes and sizes. From straight lengths to 23, 45, 90 and 180 degree bends of varing inner diameters. Then there are reducers, either straight or curved that allow you to simply step up or down in diameter sizing. They are all available in either a black or blue colour.

As you can see, the catalogue of silicone hoses makes plumbing in an air induction system achievable, no matter how many twists and turns it may have.

Cool or cold air works best in the combustion process as it is denser than warm or hot air. Turbochargers run hot exhaust gas right next to intake air when in operation. This heats the air going to the combustion chamber. To cool it down a good turbo installation will run an intercooler. The intercooler works like a coolant radiator. Hot air enters one end, flows through it and is cooled by airflow going through the intercooler. It comes out the other end cooler and denser which aids combustion.

A throttle bodys main role is to control air flow to the engine. Your accelerator pedal hooks up to it and it has a large round butterfly valve in a tube that when idling is fully closed. When accelerating flat out the butterfly valve is fully open. When closed and the engine is idling, there is a small passage with an adjustable screw for air that bypasses the butterfly valve.

It usually has provisions for a throttle position sensor (butterflies position) and a MAP (Manifold Absolute Pressure) sensor which is located behind the butterfy valve.
