I keep reading people refer to their UIM and single or dual hone. All SVT UIM manifolds were single hone, via the same spec, from the factory and flow in the low 170 cfm range. Where did the idea originate that some SVT have dual hone UIM's?

The '99 model year meant more horsepower for the SVT Contour, increasing it to an even 200. This was accomplished through more aggressive use of the Extrude Hone Powerflow process. The EEC-V module was also recalibrated for increased torque.
