Product Description

The Skunk2 Tuner Series Stage 2 Camshaft Set (part 305-05-0145) is engineered for enthusiasts building Honda/Acura B-Series DOHC VTEC engines (1.6L-1.8L) who want significant performance gains while maintaining strong drivability. With its refined lift and duration profile (approx. 264°/12.27 mm intake, 266°/11.81 mm exhaust) the set delivers an estimated +15-20 hp and +16-20 lb-ft of torque in properly built engines with supporting mods.

Manufactured with precision CNC machining from high-quality materials, these camshafts are built for durability, high-rev capability and strong VTEC performance. They are ideal for naturally aspirated or lightly forced engines, provided the intake and exhaust flows are upgraded and the valvetrain strengthened. Installation requires upgraded valve springs, retainers, and tuning for optimal performance.
