      Performance and Fuel Economy. Unleash your Sierra's hidden power with a Proven Ground C&L Series Throttle Body Spacer. The C&L Series throttle body spacer increases plenum volume to improve low to mid range torque. This Throttle Body Spacer not only improves performance, but with its unique “Spiral Bore” design it also improves fuel economy. The spiral bore "spins" the incoming air to provide superior atomization of the air fuel mixture for better combustion.

      No Tune Required. This Proven Ground C&L Series Throttle Body Spacer is designed to improve the performance of your V8 powered Sierra without the need of reprogramming its computer. The engineers at Proven Ground really did their homework to improve your truck's power using the factory tune.

      Billet Aluminum Construction. Proven Ground manufactures their C&L Series Throttle Body Spacer from high quality billet aluminum. CNC machined to precise specifications, this Throttle Body Spacer is completed in a black anodized finish for good looks and long lasting corrosion resistance.

      Simple, Bolt-On Installation. Proven Ground engineered their C&L Series Throttle Body Spacer to be a simple bolt-on upgrade. Featuring brand new hardware and gasket, installation can be completed in under an hour with just simple hand tools. Easy to follow instructions are included.

      Application. This Proven Ground C&L Series Throttle Body Spacer is designed to fit 2014-2023 5.3L GMC Sierra 1500 models with a stock/factory throttle body installed.
