Throttle Body Spacer LT1/L86

The Throttle Body Spacer LT1/L86 from ICT BILLET is a precision-engineered intake manifold spacer designed to optimize airflow dynamics on modern GM small-block engines. Built for enthusiasts and professionals seeking measurable gains in throttle response and mid-range torque delivery, this spacer addresses the inherent restriction created by direct manifold mounting on LT1 and L86 platforms. Whether you're tuning a C8 Corvette, Camaro SS, or LS-based platform swap, this component fits seamlessly into any serious performance modification strategy.

Machined from billet aluminum and finished to exacting tolerances, the Throttle Body Spacer LT1/L86 creates a controlled air gap between the throttle body and intake manifold plenum. This separation increases charge cooling, extends the fuel charge path to improve atomization, and reduces manifold heat transfer to the incoming fuel mixture—all factors that contribute to denser combustion charge and better volumetric efficiency. The spacer's 5.3 x 5.8-inch profile integrates cleanly with OEM mounting points while maintaining full compatibility with stock gaskets and fasteners, ensuring installation reliability without custom fabrication or port matching.

Ideal for owners running turbo kits, supercharger systems, or aggressive fuel mapping, the Throttle Body Spacer LT1/L86 delivers maximum benefit on modified engines where charge temperature control becomes critical to knock suppression and calibration stability. Installation requires no special tools beyond a socket set, making it accessible to both professional shops and committed home garage builders. At just 0.48 lbs, weight penalty is negligible, while the minimal cost-to-performance ratio makes this a no-regrets upgrade for any LT1 or L86 build targeting real-world drivability improvements.
