Kelford Cams 256 / 260 Street Camshaft – Subaru STI

Description

The Subaru STI EJ257B engine features dual AVCS (Active Valve Control System). This feature enables the builder to extract massive power while retaining great low end driveability. The Kelford range of camshafts feature a very new camshaft design technology termed ‘ICE’. This design technique results in a efficiency gain for these engines. No other aftermarket camshaft company offers this approach for the EJ25 engine platform.

The Kelford 220-A is a cam profile setup for the near stock engines. The cams feature a 256 / 260 duration, 9.55mm / 9.50mm Lift. Ideal for 36mm restrictor classes.
