MSD Atomic Throttle Bodies

If you're upgrading the intake manifold on your LS engine, then you'll also want one of these MSD Atomic throttle bodies. They feature a parabolic design for precise control, smoother off-idle response, and improved part-throttle drivability. The throttle bodies are manufactured from billet aluminum, with a stainless steel shaft and contoured inlet profile—which outflows the competition's big bore throttle bodies. A robust throttle cam assembly uses a 3-plate design for smooth operation, while the dual ball bearing shaft offers less shaft twist and better signal stability.
