Gain an extra 10-15 hp and retain your factory idle and low-speed emissions with Skunk2&rsquos Tuner Series Stage 1 Camshafts, our introductory line of high-performance camshafts for Honda&rsquos B16/ B17/ B18 VTEC engines. Tuner Series Stage 1 Camshafts are designed to optimize horsepower and torque on mildly modified engines. As a result, VTEC crossover is dramatic, allowing for that classic primary-to-secondary surge.

What the Skunk2 305-05-0140 B-Series Camshaft Improves

Compared to stock camshafts, the Skunk2 Stage 1 profile offers:

• Increased valve lift

• Slightly longer duration

• Improved cylinder head airflow

• Stronger VTEC engagement

These changes help increase power in the midrange and upper RPM band without sacrificing idle quality.

For daily driven Hondas, this balance makes Stage 1 one of the most practical cam upgrades available.

Whats more, Tuner Series Stage 1 Camshafts are also CARB-approved and remain the only high-performance, B-series camshafts legal for road use. No other line of high-performance camshafts even comes close to Skunk2&rsquos Tuner Series. First introduced in 1999, Tuner Series Camshafts are manufactured from the same proprietary, high-quality cores as Skunk2’s more aggressive Pro Series Camshafts, are CNC ground, and feature unique profiles and lobe shapes that emphasize an exceptional idle and low emissions.

Ideal Build Scenarios

The Skunk2 305-05-0140 camshaft works best for:

✔ Naturally aspirated street builds

✔ Budget performance upgrades

Many B-series engines with bolt-ons and proper tuning can see noticeable improvements in throttle response and high-RPM power.

Skunk2 camshafts deliver unparalleled power as a result of continual, extensive development and testing. By utilizing advanced manufacturing techniques and the latest computerized simulation and modeling equipment, Skunk2 camshafts are able to deliver maximum power across the entire powerband. Skunk2 designs and tests all of its camshafts in-house to ensure the highest quality and performance. Each camshaft is manufactured of newly revised chill-cast, billet camshaft blanks that have increased torsional strength, improved durability characteristics, and reduced frictional effects. All Skunk2 camshafts are ground to exact specifications using state-of-the-art CNC cam grinding machines equipped with cubic-boron grinding wheels and feature hardened, wear-resistant lobes and surfaces.

Recommended Supporting Modifications

To maximize the performance benefits of the camshaft, supporting upgrades are recommended:

• Performance intake manifold

• High-flow header and exhaust

• Adjustable cam gears

• ECU tuning (Hondata or chipped ECU)

While Stage 1 cams can work with stock valve springs, upgraded springs are recommended for higher RPM reliability.

Performance Benefits

With proper tuning and supporting modifications, the Stage 1 camshaft can deliver:

• Stronger mid-range torque

• Improved VTEC crossover response

• Better top-end horsepower

• Increased overall engine efficiency

This makes it an excellent upgrade for enthusiasts who want noticeable performance gains without sacrificing daily usability.
