MSD Throttle Body Replacement Tbi Cast Aluminum Natural Atomic Efi 2905

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 profilewhich 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.
