Kelford 220D Dual AVCS Camshafts 08+ WRX STI

After months of research and development, Kelford Cams are proud to release their new range of camshafts for the Subaru WRX STI EJ257B engine. This engine is found in the 2008-current STI (and some earlier Legacy models). This new engine features dual AVCS (Active Valve Control System) Factory power rating is 407nm @ 4000 rpm and 221kw @ 6000 rpm. This engine is perfect for the ‘Tuner market’ Dual AVCS offers the tuner the ability to extract massive power whilst retaining great low end driveability. The Kelford range of camshafts feature a very new camshaft design technology we term ‘ICE’. This design technique results in a combustion efficiency gain for these engines. No other aftermarket camshaft company offers this approach.
