Abstract: An intake manifold for an internal combustion engine having at least one runner having a top end, a bottom end, a front side, and a back side defining a hollow interior space wherein the top end has a first height greater than a second height of the bottom end, and a port for receiving air into the hollow interior space, the back side having cylinder holes aligning with cylinder head openings of the internal combustion engine and bolt holes for receiving bolts, each bolt having a bolt head and a bolt thread, the front side having access holes aligning with the bolt holes, such that the intake manifold can be secured to the internal combustion engine with no portion of the bolt thread lying within the hollow interior space of the intake manifold thus preventing obstruction of air circulation through the hollow interior space.
