The unique throat design of Torque-Curve technology spacers (exclusively from Hamburger's and Trans-Dapt Performance) is proven, through dyno and road testing, to perform better than both stock and a leading competitor's spacer design. Torque-Curve's design provides significantly more horsepower and torque, and they do not have the annoying whistle under driving conditions, typically associated with throttle body spacers.

At partial throttle, a negative pressure zone is created on the upper, backside of the throttle blade. This condition creates turbulence that disrupt the introduction of air into the vehicle's intake manifold, slowing airflow, and resulting in less available power. Ultimately, Torque-Curve EFI Spacer's proprietary design improves your engine's performance and fuel efficiency. Improved fuel efficiency can also translate into better fuel mileage, if you can resist the urge to enjoy the sensation of the additional torque in the seat of your pants.

Testing of Torque-Curve's design on a 2004 4.8L GM truck (spacer #3262) yielded 55 ft.lbs. more torque, and 38 HP more than stock. The same testing also demonstrated 29 more ft.lbs. of torque, and 25 HP more than a well known leading competitor's spacer on the same vehicle, under the same test parameters.

Hamburger's MPFI spacers are 100% CNC machined from 6061-T6 aluminum, come complete with all the necessary mounting hardware, and are backed by a limited lifetime warranty. Spacer models are currently available for GM, Dodge and Ford vehicles, as well as, Nissan Titan and Toyota Tundra Trucks.
