In automobiles, intake manifold is a system of passages that is used for transmitting combustion mixture to each and every intake port in the cylinder heads
. Engine breathing improves when intake manifold is designed in such a way for optimizing the pressure pulses in the air intake system
. Automobile market is flooded with many types of intake manifolds to suit different applications. Innovative multi layer design, high performance, lighter, high tensile strength, improved consistency, enhanced reliability, quick to install, easy to maintain and greater resistance are some of the chief features of modern intake manifolds available in the automotive market. A typical intake manifold is mounted between cylinder heads located in an engine. Usually intake manifolds are made of different materials namely cast iron, aluminum, stainless steel, copper, bronze, brass, nickel, plastic etc.
