102mm 4 Bolt Throttle Body + Throttle Cable + TPS IAC For GM Gen III LS1 LS2 LS6

102mm 4 Bolt Throttle Body for GM Gen III LS1 LS2 LS6

This 102mm four bolt throttle body kit includes a matching throttle cable, TPS, and IAC, designed as a complete air intake upgrade for GM Gen III LS1, LS2, and LS6 engines.

Overview

This 102mm throttle body is a high-flow air intake component built for GM Gen III LS1, LS2, and LS6 engines. The larger 102mm bore allows more airflow than the factory unit, supporting modified combinations that need extra volume. The kit ships with a throttle cable, throttle position sensor, and idle air control valve so the install can be completed in one go. It suits builders and enthusiasts assembling a performance intake on LS-based platforms.

Built For Performance

• 102mm bore for increased airflow over stock throttle bodies
• Four bolt mounting pattern matches Gen III LS intake manifolds
• Includes throttle cable, TPS, and IAC for a complete install
• Aluminum body construction with a clean machined finish
• Throttle blade and shaft sized for the larger 102mm opening
• Sensors and cable included to reduce sourcing extra parts

Fits These Machines

• for GM Gen III LS1 engines with a four bolt throttle body flange
• for GM Gen III LS2 engines with a four bolt throttle body flange
• for GM Gen III LS6 engines with a four bolt throttle body flange

On-The-Job Use

• Performance intake builds on LS1, LS2, and LS6 swaps
• Supporting airflow needs on cam and head upgrades
• Replacing a worn or undersized factory throttle body
• Custom engine builds requiring a larger throttle opening

Specs At A Glance

Good To Know

Q: Will this 102mm throttle body work with my stock tune? A: A larger bore usually changes airflow enough to need a tune adjustment for idle and driveability. Plan on a recalibration after install for best results.

Q: Do I need a different intake manifold for the four bolt pattern? A: The four bolt flange must match your manifold, so check your existing bolt pattern before ordering. Many Gen III LS intake manifolds use this configuration.

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