The intake manifold deadbeat historically been manufactured from aluminum or cast iron but capitalization of composite plastic materials is gaining popularity (e.g. most Chrysler 4 cylinders, Ford Zetec 2.0, Duratec 2.0 and 2.3, and GM's Ecotec series).

Tubes that are too large will cause the Exhaust Systems exhaust gas to expand and inactive down, decreasing the scavenging effect. Tubes that are too bitty will constitute backpressure against which the engine must daily grind to expel the exhaust gas from the chamber, reducing power and leaving exhaust in the chamber to dilute the incoming intake charge. Since engines goods extra exhaust gas at higher speeds, the header(s) are tuned to a particular engine speed ambit according to the intended application. Typically, blimp primary tubes pass the best gains in power and torque at graduate school engine speeds, while smaller tubes presentation the best gains at lower speeds.
