Throttle Body Ultimate LS 92mm w/Sensors

The Throttle Body Ultimate LS 92mm w/Sensors from FiTECH Fuel Injection is engineered for LS engine builders and performance enthusiasts seeking precise air-intake control and seamless EFI integration. This 92mm throttle body assembly replaces restrictive factory units and enables tuners to maximize airflow while maintaining accurate fuel delivery across the entire RPM spectrum. Whether you're building a street engine, race application, or retrofitting an older LS platform with modern fuel injection, this unit delivers the responsive throttle control and reliability that serious engine builders demand.

The 92mm bore diameter provides optimal airflow velocity without sacrificing low-end torque response, a critical balance that separates quality throttle bodies from marginal upgrades. Built-in sensors eliminate the need for external air-intake temperature and barometric pressure modules, simplifying wiring harnesses and reducing installation complexity on custom EFI systems. The integrated sensor package feeds real-time data to your FiTECH ECU, allowing the fuel-injection computer to continuously adjust pulse-width and timing for maximum efficiency. Precision machining and direct-fit LS bolt-pattern compatibility ensure leak-free sealing and factory-level durability in high-heat engine bay environments.

LS engine swappers, hot-rod builders, and anyone running FiTECH's closed-loop fuel-injection system will benefit from this throttle body's plug-and-play sensor integration and repeatability. Installation pairs seamlessly with FiTECH ECUs (Gen 2.0 or newer) and does not require expensive adapter plates or aftermarket intake modifications on standard LS applications. The compact 5.9 x 3.6 x 7.6-inch footprint fits tight engine bays while the lightweight 2.4 lbs construction minimizes inertial mass, improving throttle response and reducing overall drivetrain parasitic losses.
