Skunk2 Tuner Stage 3 Camshaft K-Series K20A2 (305-05-0230)

The Tuner Stage 3 Camshaft by Skunk2 Racing is the premier line of high-performance camshafts for Honda's K-series engines. You can be sure in no loss of drivability as these camshafts will surpass all other Skunk2 Tuner models from idle to redline. 

Especially designed for mid - high level modified vehicles using the 3 Lobe VTEC K20A/ K20A2/ K20Z1/ K20Z3 and K24A2 engines or cylinder heads. These camshafts are also a great match for vehicles with aftermarket intake manifolds, big-tube header, light - heavy cylinder head work, vast compression changes and full exhausts.

Do you want to feel a powerful gain in horsepower? 

Skunk2's vigorous in-house testing methods have proved average gains in horsepower to be in the range of +30-35 with larger gains reaching mid-level torque and higher-level RPM horsepower. Their specific design allows your vehicle to boost power at high-level rpm whilst optimising horsepower and torque with engines promoting free-flowing intake and exhaust tracts, elevated compression and enhanced valve train. If that isn't enough they also guarantee the ability to retain factory idle and low-speed emissions. 

Years worth of street and drag racing achievements have allowed Skunk2 to develop the Tuner Stage 3 Camshaft.Their unmatched delivery of maximum power across the whole powerband has enabled Skunk2 camshafts to remain unparalleled in their technology without any other high-performance camshafts even coming close as competition. Impressively, they are still being relied on by the the world's top road racing and drag racing teams today.

The Skunk2 Tuner Stage 3 Camshaft utilises cutting-edge Fast Ramp and AMAX profile technology, which advances overall performance and shows results in an unrivalled response from idle to redline. 

AMAX - Designed by Skunk2 to maximize the area underneath the lift curve but without adjusting it's accuracy or stability from the valve-train. 

Fast Ramp - Using the same technology found in Formula One racing, where seat timing is decreased, resulting in added cylinder pressure and increased torquey whilst without compromising valve-train longevity.

Skunk2's profiles contain more refined duration than other competitors' at lifts above 1mm, resulting in greater efficiency and enhanced power. By applying advanced manufacturing techniques and the latest computerised simulation and modeling equipment, you will be sure to experience supreme quality and improved overall performance. 

The Skunk2 Tuner Stage 3 Camshaft is carefully crafted from high-strength, hollow, iron-alloy cores featuring next generation profiles that highlight an extraordinary idle and low emissions. Every Skunk2 camshaft is made to exact specifications using state-of-the-art CNC machined equipped with cubic-boron grinding wheels and feature hardened, wear-resistant lobes and surfaces.
