ACT Performance Components – Performance

At ACT we research and fully develop products before they come to market, we have been developing TVR upgrades since 1997, we now have a carbon fibre plenum for the Alfa V6 , this has been very popular and has achieved respectable performance and power increases. We also have a wide range of general use air-boxes .


Below are some power graphs, from 2002 showing a before and after figures.
