What can I say, this is a throttle body gasket. Is there more horsepower, torque, fuel consumption? I really do not know it. I need this spacer as I installed Howell TBI fuel injection on my '83 Jeep CJ7 with 258 engine and didn't want to draw hot air through the exhaust manifold. The simple fix is a cold air intake, except it doesn't expose the valve cover. The Trans Dapt spacer was easy to install and helped solve my spacing issue.
