More Info:
This range of Kelford Camshafts to suit the Subaru STi EJ257B dual AVCS features the same successful lobe designs used on the earlier engines. The Dual AVCS on this engine is a great tool for the tuner to provide a greater operating range. The Kelford range of camshafts feature a unique camshaft design technology called “ICE” or Improved Combustion Efficiency. This “ICE” split duration design has in turn created a significant combustion efficiency gain for these engines. No other aftermarket camshaft company offers this unique technology.
Please note that the correct valve spring selection will depend on the installed height in your particular cylinder heads. Please contact Kelford to discuss the correct valve spring selection.
