LTX Throttle Body 103mm

The Soler Performance SE8223-103NE is a high-performance billet 103mm LTX throttle body engineered for enhanced engine modification and drivability. It boasts a 16 Ra Microinch, diamond-polished surface finish for lower skin friction and a dimpled pattern on the shaft trailing edge to optimize airflow. This throttle body is designed for exceptional high flow capacity, rated at 1550 +/- 50 SCFM @ 20” H2O at WOT. It offers immediate response right off idling without hesitation or stumble, contributing to a more nimble and spirited driving experience. The calibration ensures linearization and smoothing of the power curve for predictable response and crisper shifts. While it does not require tuning to run, optimal performance is highly recommended. Important notes for installation include the requirement for an aftermarket inlet duct/CAI or expandable coupler (P/N: SE1000-CLPR-KT). Stock manifolds/superchargers will need an Adapter Kit (P/N: SE8223-103-87AD), unless the manifold or supercharger is ported to at least 102mm. The dual-purpose hole pattern allows for direct fitment to MSD, LT1/2/4 manifolds/superchargers, or aftermarket superchargers, with the outermost pattern fitting the LT5 (ZR1) supercharger. It is fully tested before shipping for sensor and motor operation, response time, and airflow, ensuring zero intrinsic calibration issues. Inlet Coupler & Transitional Spacers are available for purchase separately. This throttle body is compatible with a wide range of Chevrolet and Cadillac models, including Corvette C7 and C8 generations, Camaro SS/ZL1, CTSV, CT5-V BlackWing, Silverado, Suburban, Sierra, and Yukon.
