Big Airflow For Big Power LS Builds

The HPI LS 4-bolt 102MM billet throttle body is designed for performance builders who are done playing small. Built from precision CNC-machined 6061-T6 billet aluminum, this throttle body is engineered to increase airflow capacity while keeping weight down and quality consistent.

HPI high-flow throttle bodies are developed using modern computer modeling and testing equipment to maximize flow per square inch of cross-sectional area. That means your intake setup gets the air it needs without bottlenecking your combination. Product details verified from the HPI listing. :contentReference[oaicite:0]{index=0}

Performance Details That Matter

• LS 4-bolt throttle body design
• Large 102MM opening for high-airflow applications
• Precision CNC-machined billet 6061-T6 aluminum body
• Brass throttle blade helps reduce vibration and thermal expansion
• Aircraft-quality throttle blade hardware is Loctited and peened for secure retention
• Machined throttle shaft helps increase available cross-section for airflow
• Includes dual 3.5" Y quick seals for a cleaner air-tight seal

Built For Builders Who Hate Restrictions

Your engine can only make power with the air and fuel you give it. If your intake setup is choking the combination, you are leaving performance on the table. This 102MM billet throttle body helps open the door for better airflow, sharper response, and a cleaner high-performance intake setup.

Whether you are building an LS swap, street car, drag setup, boosted combo, or naturally aspirated performance build, this throttle body gives your intake system a serious upgrade point.
