Skunk2 Racing 305-05-7000 for Acura/Honda K-Series Drop-In Camshaft

Key Features

The Skunk2 Drop-In Camshaft provides improved performance while maintaining compatibility with factory valvetrain components.

Specifications

• Part Number: 305-05-7000

• Product Line: Drop-In Series

• Engine Compatibility: Honda / Acura K-Series engines

• Material: High-quality billet steel

• Design: Performance cam profile for improved airflow

• Installation: Compatible with factory valve springs and retainers

This camshaft provides increased lift and duration compared to stock camshafts, improving engine breathing while maintaining reliability.

Skunk2 Racing’s DIC (Drop-In Camshafts) are designed as a performance upgrade to stock or near stock vehicles running the 3 Lobe VTEC K20A/ K20A2/ K20Z1/ K20Z3 and K24A2 engines or cylinder heads. These camshafts will outperform the stock camshaft from idle to redline with no loss in drivability. DIC’s are compatible with stock valve springs and retainers; however, a valve spring upgrade can always be considered beneficial.

Performance Benefits

Upgrading to a Skunk2 drop-in camshaft can improve overall engine performance without requiring a full engine build.

Benefits include

• Increased horsepower and torque

• Improved engine airflow

• Stronger mid-range and top-end power

• Compatible with stock valvetrain components

• Ideal for bolt-on performance builds

For many enthusiasts, this is one of the easiest internal upgrades to unlock additional power from the K-series platform.

Our DIC’s incorporate the same cutting-edge Fast Ramp and AMAX features as our professional BMF and Ultra lines, which are responsible for increasing overall performance and producing unmatched response from idle to redline. You can expect optimized mid-range and top-end horsepower/torque with peak power moved up the RPM band, producing a seamless VTEC crossover!

Fast Ramp – The same technology used in Formula One racing, where seat timing is reduced, which results in additional cylinder pressure and more torque but without compromising valvetrain longevity.

Compatible K-Series Engines

The Skunk2 305-05-7000 Drop-In Camshaft is designed for several Honda and Acura K-series engines, including:

• K20A / K20A2

• K20Z1 / K20Z3

• K24A / K24A2

These engines are commonly found in vehicles such as:

• Honda Civic Si

• Acura RSX Type‑S

• Honda Accord

It is also popular among enthusiasts building K-swap projects.

AMAX – A Skunk2 design that simply maximizes the area under the lift curve but without compromising reliability or valvetrain stability. Skunk2’s profiles feature more duration than competitors’ at lifts above 1mm, resulting in greater efficiency and more power.

Independent tests have shown average gains to be in the neighborhood of +15-18 horsepower with the occasional +20-22 hp on really efficient combos! Drop-In cams are indeed drop-in but proper installation (checking all critical clearances and degreeing) and tuning are still necessary and many times may be the difference in the numbers you will see.

Performance upgrade to mildly modified vehicles running 3 Lobe VTEC K20 / K24 engines
Fast Ramp & AMAX Technologies
Horsepower Gain: 15-22
Does NOT require the use of aftermarket valvetrain components

While the camshaft is designed as a drop-in upgrade, performance gains improve when paired with common bolt-ons.

Recommended upgrades include:

• Performance cold air intake

• High-flow exhaust system

• Larger throttle body

• Adjustable cam gears

• ECU tuning

Together, these modifications allow the engine to fully take advantage of the improved camshaft profile.

Why Choose Skunk2 Racing?

Skunk2 Racing has been a trusted name in Honda performance for decades. Their engine components are developed using real race-engine data and extensive dyno testing to maximize power while maintaining reliability.

The Drop-In Series camshafts are designed specifically for enthusiasts who want measurable power gains without the complexity of a full race engine build.

Final Thoughts

The Skunk2 Racing 305-05-7000 Drop-In Camshaft is an excellent upgrade for Honda and Acura K-Series engines looking for improved performance without extensive engine modifications. With a performance-focused cam profile and compatibility with factory valvetrain components, it offers a straightforward way to increase horsepower and enhance engine response.

Because sometimes the best upgrades are the ones that add power without requiring a complete engine teardown.
