摘要

A performance intake manifold ranks as the leading bolt-on upgrade in a performance-minded build. Good examples can work wonders, while the wrong choice can spell doom to the combination. The Edelbrock AirGap two-planes are among the best and most versatile. At first blush it might seem that the intake manifold is one of the simplest components on an engine. After all, the purpose of the intake is essentially to provide a series of passages to join the carburetor with the intake ports of the heads. That appears to be a fairly simple job description, and on the surface, it is. But, there is big power in just how those passages are connected. In a simple world, a design draftsman could just draw some straight lines between point "A" and point "B," and lay out a manifold with a series of corridors, using right-angle turns to lead were the passages need to go, kind of like hallways in a house. Well, in the old days, it's surprising how many manifolds were designed just that way. Though those early intakes fulfilled their job description, they were found to be far from ideal, and a great deal of potential power was needlessly left on the table. It didn't take long for enterprising hot rodders to see the shortcomings in manifold design as applied to early OEM engines, and an industry was born. Aftermarket intake manifolds of widely varied design have been offered over the ensuing yean some good, some decidedly poor, but all cast with the idea of improving on the efficiency of the factory designs in search of more horsepower.
