The engines that power the vehicles we drive are exceptional machines. They're capable of generating insane amounts of power in a relatively confined space, and they can generally be expected to ...

In the first installment we dealt with the essentials of spec intake manifolds. The story was intended to establish a level of understanding that would enable more specific information to be helpful, ...

In this study, the effect of intake manifold geometry on cylinder-to-cylinder variation was investigated considering the volumetric efficiency, early tumble development, turbulent kinetic energy, and ...

Bolting on an aftermarket intake manifold has long been the introduction to hands-on hot rodding. Improved looks, performance, and, often, fuel economy can be just an intake swap away. Not to mention ...
