EJ257B WRX STi Dual AVCS (2008-Current)
Perfomance Cams for Subaru EJ257B WRX STi Dual AVCS (2008-Current)
This range of Kelford Camshafts to suit the Subaru WRX 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 us to discuss the correct valve spring selection.
In addition to our catalogue range, we can manufacture custom cams to your specifications, or design a profile to suit your specific application.
