High lift 272 degree racing camshafts. Requires cylinder head modification to fit. Suits well built competition motors. Good on E85 fuel. Must have shimless buckets and aftermarket ECU.
This range of Kelford high performance camshafts is to suit what we call the USDM EJ25 engine (2005-2008) equiped with Subaru's awesome AVCS (Active Valve Control System) on the intake cams only.
Suites from 400-600 hp range
