Atomic LS Throttle Body 103mm, 4 Bolt

MSD's LS Throttle Body answers the need for a high quality throttle body with a mechanical throttle mechanism that bolts to most factory and aftermarket intakes. The parabolic bore form design helps deliver excellent drivability characteristics during part throttle that typical billet straight bore throttles just can't deliver. We incorporated factory style bearings and seals on the throttle that can withstand years of use on the street or strip.

• Parabolic design for precise control, smoother off-idle response and improved part-throttle driveability
• Contoured inlet profile outflows the competition's big-bore throttle bodies
• Less shaft twist for superior TPS signal stability
• Billet body with stainless steel shaft
• Robust throttle cam assembly, featuring a three-plate design
• Dual ball-bearing design offers shaft stability and smoother operation
• 4-bolt mounting for easy installation
