102mm Aluminum 4 Bolt Throttle Body & TPS IAC For GM Gen III LS1 LS2 LS6 LS7 LSX

102mm Aluminum 4 Bolt Throttle Body & TPS IAC for GM Gen III LS1 LS2 LS6 LS7 LSX

This 102mm aluminum 4 bolt throttle body with TPS and IAC is a direct-fit air intake component for GM Gen III LS series engines, letting your build pull more air for stronger throttle response.

Overview

This 102mm aluminum 4 bolt throttle body and TPS IAC assembly is built for GM Gen III LS series engines, making it a strong choice for builders chasing more airflow. The cast aluminum body houses the throttle blade, throttle position sensor, and idle air control in one bolt-on unit. It suits LS1, LS2, LS6, LS7, and LSX based projects where a larger throttle body is part of the plan.

Built For Performance

• 102mm bore size for increased airflow over factory throttle bodies
• Cast aluminum body for strength and heat resistance
• Four bolt mounting pattern for LS series intake manifolds
• Integrated throttle position sensor for direct plug-in signal
• Integrated idle air control valve to manage idle speed
• Designed for GM Gen III LS series engine families

Fits These Machines

• for GM Gen III LS1 equipped vehicles
• for GM Gen III LS2 equipped vehicles
• for GM Gen III LS6 equipped vehicles
• for GM Gen III LS7 equipped vehicles
• for GM Gen III LSX based builds

On-The-Job Use

• Throttle response upgrades on LS swapped project cars
• Naturally aspirated builds needing more intake airflow
• Forced induction setups that need a larger throttle body
• Engine swap builds using LS series intake manifolds
• Track and street performance applications

Specs At A Glance

Good To Know

Q: Is the throttle body a genuine GM part? A: No, this is an aftermarket replacement throttle body built for GM Gen III LS series engines, not an original GM unit.

Q: Will I need a tune after installing it? A: A larger bore throttle body usually changes airflow enough that a recalibration is recommended for correct idle and throttle response.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
