$999.00
SKU
kef220-C
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.
High lift 272 degree racing cams to suit well built competition engines. These cams work particularly well with E85 fuel. Requires cylinder head modification to fit.
