Camshaft, Track Mod, Single AVCS, EJ25

CJM Components Track Mod Camshaft

These cams were designed and developed specifically as track-focused performance camshafts for Subarus making up to 750 HP. Upgrading to performance cams allows the engine to breathe more efficiently by improving valve timing and lift, increasing airflow, enhancing top-end power, and supporting horsepower levels beyond what factory cams can handle. Despite their increased performance capability, the CJM Track Mod profile maintains predictable drivability suitable for dual-purpose street and track use.

Upgraded valve springs are recommended but not required. We suggest using the CJM Track Mod Dual Spring Package

Break-In: A proper camshaft break-in procedure using high-zinc oil is mandatory to ensure long-term durability and peak performance.

Professional Installation: Installation should be performed by an experienced technician familiar with Subaru timing systems and AVCS functionality.

Fitment: These CJM Track Mod cams are designed exclusively for USDM Subaru engines equipped with single AVCS (intake only).
