      • Performance Single Plane Carbureted Intakes for LS Racing Engines

      GM LS engines have been the number one choice in engine conversions for drag racing applications due to their superior strength and versatile design. JEGS LS Single Plane Intake Manifolds allow you to use a square bore carburetor or throttle body fuel injection replacing the standard computer-controlled multi-port fuel injection setup. These intake manifolds are designed for LS1, LS2 & LS6 racing engines and provide maximum power & performance from 2500-7000 RPM. The OE-style intake port o-ring seals make installation a breeze.
