Swirl-Torque TBI Spacer

The Swirl-Torque TBI Spacer from TRANS-DAPT is a precision throttle body spacer engineered for Small Block Chevy and GM midsize V6 engines in 1992–95 vehicles. This aluminum spacer installs between your intake manifold and throttle body to improve air charge distribution and combustion chamber velocity. Mechanics and performance enthusiasts rely on spacers like this one to unlock modest but measurable gains in throttle response and low-to-mid-range torque without requiring major engine modifications.

The Swirl-Torque TBI Spacer uses a 1-inch thickness to create a strategic plenum volume that enhances air swirl as it enters the intake ports, promoting better fuel atomization and more complete combustion. Cast from aluminum and finished in natural bare metal, the spacer arrives with all necessary gaskets and hardware for a bolt-on installation. The thermal separation between throttle body and manifold also provides minor heat isolation, reducing intake air temperature during extended driving. At just 1.58 lbs, the spacer adds negligible weight while delivering tangible drivability improvements on stock or mildly modified engines.

This spacer fits Small Block Chevy and V6 engines in 1992–1995 GM midsize trucks and SUVs, making it ideal for owners of Blazer, S10, and similar platform vehicles. Installation requires removal of the throttle body, gasket replacement, and torque verification—a straightforward weekend job for any mechanic with basic hand tools. The included gasket set and hardware eliminate sourcing fasteners separately, and the aluminum construction resists corrosion for long-term reliability. Whether you're building a mild performance package or restoring original driveability on a carbureted or TBI-equipped engine, the Swirl-Torque TBI Spacer offers proven results at an accessible price point.
