5.5L V8 LT6 Modified Ported Throttle Body Pair

The Soler Performance SE3793-91 throttle bodies are a premium upgrade for the 5.5L V8 (LT6) engine found in the 2023+ C8 Corvette Z06. These are not simply stock throttle bodies; they have been extensively modified, ported, and calibrated by Soler Performance to optimize airflow and engine response. Key features include optimized active contours with sonic flow nozzles, a porting taper with an upstream bore and velocity stack, and a greater discharge coefficient at the plate/blade interface. The shaftless design on the high-pressure side of the blade allows for a larger effective bore of 91 mm, leading to a significant increase in wide-open throttle flow. Specifically, they achieve 1165 +/- 20 SCFM, which is a 20% increase over the OEM 970 SCFM. The aluminum construction is finished with a 16 Ra microinch, diamond-polished surface for superior smoothness. The product is sold only as a pair, replacing OEM P/N: 12713793 and 12729502.
