Product Description

The Skunk2 Tuner Series Stage 1 Camshaft Set (part 305-05-0140) is engineered for Honda/Acura enthusiasts running B-series DOHC VTEC engines (1.6L-1.8L) who seek a performance upgrade without sacrificing drivability. With a modest lift and duration increase, the set offers approximately 10-15 hp gain and improved torque in the mid to upper rpm range, while retaining a factory-like idle and reliable valvetrain compatibility.

Manufactured from high-quality materials with precise CNC grinding and hardened lobes, these camshafts are built for longevity and performance. They are rated for a broad rpm range (approx. 1,500-8,500 rpm) and are well suited to mildly modified naturally-aspirated or lightly boosted B-series VTEC builds. Installation is straightforward with stock springs and retainers in many cases - but proper tuning of ECU, intake, and exhaust is highly recommended for best outcomes.

Fitment is confirmed for the listed years and models above. **Fitment confirmed through 2001. 2025 coverage unconfirmed at time of listing.** If you are running a specific JDM variant, swap-engine or non-VTEC configuration, confirm compatibility accordingly.
