The Katech LS3/LS7/L99 Ported Throttle Body (KAT-A7068) is a new GM 90mm throttle body engineered to enhance engine performance. It features a CNC-ported design for improved airflow, a gold blade, and a 6-pin configuration, offering increased throttle response and horsepower/torque gains across the entire power band. This throttle body provides excellent drivability and does not require a core return. It is constructed from aluminum and is designed as a direct replacement for specific LS-based engines. Compatibility includes a wide range of GM vehicles: 2010-2015 Camaro SS, 2014-2015 Camaro Z28, 2011-2017 Caprice PPV, 2009-2013 Corvette Base/GS/Z06 (late 2009 models with gold blade only), 2008-2009 Pontiac G8 GT/GXP, and 2014-2017 Chevy SS. Specific model year and engine fitments, such as the 6.0L L77 or 6.2L LS3, are detailed for precise application.
