Why are these valves improve performance?
The valves are undercut at throat and provide a swirl Flow towards the edges of the valve. That promotes Improved fuel atomization, Intake stroke cooling and Better air distribution within the cylinder before beginning of ignition/combustion stroke. A real 8% increase in flow just by swapping out valves. No need for cams.
Weight is ~ the same or lighter.
I have been using the same valves for years. Since 2001 NIRA/NDRA/NHRA race season. Go to my site and see the work and parts installed on both my 944S and Conquest TSI.
