Kelford Cams for EJ257B WRX STi Dual AVCS

Genuine Kelford performance camshafts, purpose-built for the Subaru EJ257B Dual AVCS engine found in 2008-current WRX STi models. For STi owners across North America searching for Kelford cams EJ257 WRX STi, this application-specific profile range is built to work with your factory Dual AVCS system.

Why This Cam Range Stands Out

Proven Lobe Design, Refined for Dual AVCS

These camshafts carry forward the same lobe designs that have made Kelford's earlier EJ-series cams a trusted choice, adapted specifically to take advantage of the Dual AVCS system on the 2008-current EJ257B. Dual AVCS gives tuners a wider operating range to work with, and these profiles are designed to make the most of it.

ICE Technology

Every cam in this range features Kelford's ICE (Improved Combustion Efficiency) split-duration design. This approach delivers a combustion efficiency gain and is exclusive to Kelford.

Catalogue Range or Custom Grind

Choose from Kelford's established catalogue of profiles for the EJ257B Dual AVCS, or work with the team to have a custom cam manufactured for your specific build requirements. Whether you are setting up a street car or building toward a more specialized application, there is a path to the right profile.

Correct Valve Spring Selection Matters

Valve spring choice depends on the installed height in your particular cylinder heads; it is not one-size-fits-all. Before ordering, contact us to confirm the correct spring selection for your setup and help avoid valvetrain issues down the road.
