Description:

Enhance throttle response, airflow efficiency, and overall engine responsiveness on your 2025+ Chevrolet C8 Corvette ZR1 with the Soler Performance Dual 70mm Ported Throttle Body Set, Part Number SE8854-70NE. Engineered specifically for the 5.5L LT7 twin-turbocharged V8 engine, these premium performance throttle bodies are manufactured using brand-new Genuine GM OEM throttle body assemblies that undergo Soler Performance's precision porting and airflow optimization process. Featuring a 70mm effective bore, optimized active contours with sonic flow nozzles, and specially designed velocity-stack porting, each throttle body is engineered to increase airflow efficiency and reduce restriction throughout the throttle range. A diamond-polished 16 Ra micro-inch internal surface finish, optimized throttle blade interface, and shaftless high-pressure blade design further enhance wide-open-throttle airflow while maintaining smooth factory-style drivability. Designed to deliver sharper throttle response, more predictable acceleration, and improved part-throttle performance, these Soler Performance throttle bodies provide an excellent upgrade for both factory and modified C8 Corvette ZR1 applications. Sold as a complete pair of brand-new, zero-mile throttle body assemblies, this package requires no core exchange and does not require ECU tuning for installation on an otherwise compatible factory application.
