The filter is positioned to offer smooth acceleration and a noticeable performance increase, making it a suitable upgrade when upgrading to a 102mm intake path. The system emphasizes a seamless replacement for aftermarket intake setups, with emphasis on driving smoothness and reliability in high-performance applications.
BTR 102mm Throttle Body Gasket
The BTR Brian Tooley Racing gasket is engineered for precise sealing on 102mm and 103mm throttle bodies, supporting optimal performance in LS-powered setups. Made from durable gasket material, it provides heat resistance, longevity, and leak prevention under demanding conditions. This gasket is particularly relevant for engines using Trinity and Equalizer manifolds, ensuring a reliable seal that maintains consistent throttle response and fuel efficiency in high-performance scenarios.
ICT Billet LS 92mm to 102mm TB Adapter
This ICT Billet adapter is built in Wichita, Kansas from aerospace-grade USA-made billet aluminum. It adapts a 102mm throttle body to a 92mm intake manifold, allowing for flexible hardware combinations in LS builds. The adapter comes with bolts and an O-ring seal for a secure fit, enabling reliable performance across a range of LS1/LS3/LSX configurations. It’s a practical choice for builders seeking to bridge 92mm manifolds with larger 102mm throttle bodies without compromising sealing or durability.
FAST LSXr 102mm Kit
The FAST LSXr kit pairs a 102mm LSX manifold with a 102mm large-mouth billet throttle body. It is designed for GM LS engines with rectangular port heads and aims to enhance throttle response, torque, and airflow. The kit emphasizes a standard of airflow performance, with interchangeable runners to tune the power band. FAST emphasizes the advantages of alloy and polymer technology to maintain cooler intake temps, improving overall engine efficiency and power output.

The Tektall 102mm aluminum throttle body (with TPS and IAC compatibility) is designed for LS-based builds requiring a robust, high-flow intake component. The CNC-cut billet aluminum body offers high temperature and corrosion resistance, ensuring durability in demanding conditions. It is compatible with GM Gen III LS engines and is suitable for use in performance-oriented street and race applications where throttle response and air delivery are critical.
Buying Guide: Key Purchase Considerations
- Fitment and compatibility: Confirm the 102mm dimension and whether the part works with your specific manifold, throttle body, or gasket suite (e.g., 92mm-to-102mm adapters, 102mm gasket interfaces).
- Intake efficiency vs. heat: Look for components that minimize intake air temperature and maximize air velocity, such as high-flow filters, polymer components, and heat-resistant gaskets.
- Material quality and durability: Billet aluminum and high-grade gasket materials can improve longevity in high-performance applications.
- Intake routing and packaging: Ensure the chosen parts won’t interfere with hood clearance, steering, or accessory belts and that they allow easy installation and maintenance.
- Throttle response vs. power band: Some kits emphasize peak horsepower, while others optimize throttle response across RPM ranges; choose based on driving style (street vs. track).
- System cohesion: When selecting multiple components (manifolds, throttle bodies, adapters), prioritize compatibility and a balanced airflow path to avoid unintended bottlenecks.
- Installation considerations: Some parts require professional calibration or ECU tuning to maximize gains and maintain safe air-fuel ratios.
In sum, the items listed here provide a spectrum of options for 102mm throttle-body setups, from universal cold-air intake enhancements to precise gasket and adapter solutions. Each product contributes to improved airflow, throttle response, and potential power gains when paired with compatible manifolds and throttle bodies. Consider your engine build, desired performance outcomes, and installation constraints to pick the best combination for your 102mm induction path.
