E-Runners are elliptical shaped entrance runners. Elliptical runners produce higher velocity speeds than traditional square and circular port intake runners. Higher velocity means an increase in volumetric efficiency. The taper ration is also more consistent for the oval/rectangular ports in cylinder heads than the traditional circular entrance. E-Runners are available for both small and big block applications.
