91mm Throttle Body

The Soler Performance SE8223-91 is a premium, modified, ported, and calibrated throttle body designed to enhance the performance of various General Motors vehicles. With a 91 mm effective bore, it is engineered to optimize airflow and deliver a more spirited driving experience. Key features include optimized active contours with sonic flow nozzles, a porting taper, and an upstream bore with a velocity stack. The throttle body boasts a greater discharge coefficient of the plate/blade interface and a 16 Ra microinch diamond-polished surface finish. It also incorporates a shaftless high-pressure side of the blade for a larger WOT flow area, a self-cleaning throat/flow gap, dome and thread-locked screws, and a dimpled shaft trailing edge. This throttle body provides a 16% increase in airflow over OEM specifications, achieving 1128 +/- 20 SCFM at 20.4” of water vacuum. Benefits include a lower weight-to-power ratio at part throttle for improved nimbleness, linearization and smoothing of the throttle curve for more predictable response and crisper shifts, and immediate response off idle without compromising idling function. It does not require tuning and is warranty safe. The SE8223-91 fits 6.2L engines in the Corvette (C7/C8, 2014-Present), Camaro SS/ZL1 (2016-Present), Cadillac CTS-V (2016-2019) and CT5-V Blackwing (2022+), and Silverado/Suburban/Sierra/Yukon/Escalade (2014-2021). It also fits the L83 Engine (5.3L) when used with adapter kit P/N SE8223-87-80. For newer trucks and SUVs (2022+), P/N SE9160-91 is recommended. It serves as an enhanced performance replacement for OEM part numbers 12620263, 12678223, 12713774, and others.
