Torque Solution Throttle Body Spacer Torque Solution Throttle Body Spacers are designed to increase Horsepower & Torque. By creating more intake manifold volume along with a better air fuel mixture you will make more power and get better fuel economy. CNC Machined from 6061 Billet Aluminum we can assure you the fit and finish is perfect. Pair the spacer up with a Thermal Throttle Body Gasket & Intake Manifold Gasket (not all applications) for even better gains by reducing the heat transfer from your engine. For the serious racer we have also drilled and tapped the spacer for a 1/8" NPT nitrous jet or vacuum/boost reference port. - 6061-T6 Billet Aluminum - Tapped for Nitrous - Install in Minutes - Better Fuel Economy - Hard Anodized Finish - Limited Lifetime Warranty PROPOSITION 65 Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm.
