Gain an extra 20-25 hp and retain your factory idle and low-speed emissions with Skunk2’s Tuner Series Stage 3 Camshafts, our introductory line of high-performance camshafts for Honda’s B16/ B17/ B18 VTEC engines. Tuner Series Stage 3 Camshafts are designed to increase power at higher rpm as well as optimize horsepower and torque on engines featuring free-flowing intake and exhaust tracts, increased compression, and upgraded valvetrain. As a result, VTEC crossover is dramatic, allowing for that classic primary-to-secondary surge.

🔧 What Skunk2 Stage 3 B Series Camshaft Delivers

Compared to Stage 2:

• Higher lift

• Longer duration

• Stronger top-end airflow

• More aggressive VTEC crossover

Designed for engines operating 8,000–8,800+ RPM.

This cam favors high-RPM horsepower over low-end torque.

What’s more, Tuner Series Stage 3 Camshafts have helped power numerous race teams to victory over the years, reaching legendary status the world over. No other line of high-performance camshafts even comes close to Skunk2’s 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.

🏁 Required Supporting Mods (Not Optional)

✔ Dual valve springs
✔ Upgraded retainers (steel or titanium)
✔ Adjustable cam gears
✔ High compression pistons recommended
✔ Ported head
✔ ECU tuning (Hondata / standalone)

Install without proper valvetrain and tune? That’s how engines learn lessons the expensive way.

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.

⚙ Ideal Build Scenarios

• 200–230+ HP NA B-series builds

• High compression street/strip setups

• Road race applications

• Aggressive VTEC crossover tuning

If you’re daily driving in traffic with stock compression, this probably isn’t your cam.

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. Skunk2 camshafts designs are the direct result of our years of drag racing and road racing efforts. In addition to each Skunk2 project car and race vehicle, the world’s top road racing and drag racing teams have relied on Skunk2 camshafts for years. Features: Designed to increase power at higher rpm as well as optimize horsepower and torque CNC ground, featuring unique profiles and lobe shapes that emphasize an exceptional idle and low emissions
