skunk2 pro series intake manifold

The Skunk2 Pro Series Intake Manifold is a popular aftermarket upgrade for Honda and Acura enthusiasts, particularly those looking to increase the performance of their naturally aspirated or forced induction engines. Skunk2 is a well-known brand in the Honda tuning community, offering high-quality components designed for improved airflow and power gains.

Overview of the Skunk2 Pro Series Intake Manifold

1. Design:
   • The Skunk2 Pro Series Intake Manifold is designed with high-flow and high-velocity runners, which improve airflow to the engine, leading to better throttle response, mid-range, and top-end power.
   • It features a plenum that is significantly larger than stock intake manifolds, allowing the engine to breathe better at higher RPMs.
   • It is typically constructed from cast aluminum for durability and heat resistance, while also being lightweight.
2. Performance Gains:
   • The design of the manifold is optimized for mid-to-high RPM performance, making it ideal for street and track use.
   • Many users report horsepower gains in the 5-15 HP range, depending on supporting modifications such as the exhaust, intake, tuning, and whether the engine is naturally aspirated or boosted.
   • It is especially effective on engines that are heavily modified or built for high-revving applications like K-series or B-series engines.
3. Applications:
   • Skunk2 Pro Series manifolds are available for a wide range of Honda and Acura engines, including:
     • B-series: B16, B18, B20 engines (e.g., Integra, Civic)
     • K-series: K20, K24 engines (e.g., RSX, Civic, Accord)
     • D-series: D16 engines (e.g., Civic EX, Si)
   • It is commonly used in Honda Integra Type R (DC2) builds as well as Acura RSX Type S (DC5) or Honda Civic Si projects.
4. Throttle Body Compatibility:
   • The manifold is often designed to fit larger aftermarket throttle bodies, typically 70mm or 74mm, allowing for even more airflow and potential power gains.
   • It can be paired with the Skunk2 Pro Series throttle body for optimal performance, although it is also compatible with most other brands.

Features and Benefits

1. Increased Airflow:
   • The large plenum and short, straight intake runners reduce restrictions, allowing more air into the combustion chamber, which helps generate more power.
2. Improved Throttle Response:
   • By increasing airflow, the Skunk2 manifold improves throttle response, particularly at high RPMs, making it a great choice for both naturally aspirated and forced induction applications.
3. Dyno-Tested:
   • Skunk2 has tested these manifolds on a variety of setups, showing gains in both horsepower and torque, especially in the upper RPM range, where factory intake manifolds tend to fall short.
4. Direct Bolt-On:
   • The Pro Series manifold is designed as a direct bolt-on replacement for stock intake manifolds, making installation straightforward for most DIYers or professionals.
5. Race-Proven Design:
   • Skunk2’s manifold design is based on years of motorsport experience. It has been used in professional racing applications, proving its durability and performance under extreme conditions.

Considerations Before Installation

1. Tuning Required:
   • While the Skunk2 manifold can provide gains out of the box, for best results, it’s recommended to have the vehicle tuned after installation. Proper tuning ensures the engine can take full advantage of the increased airflow.
2. Supporting Mods:
   • The full potential of the Skunk2 Pro Series manifold is best realized when used in conjunction with other performance upgrades like:
     • Cold air intakes
     • High-flow exhaust systems
     • Upgraded throttle bodies
     • Cams or headwork for even more significant gains.
3. Engine Application:
   • This manifold is geared towards high-RPM performance, so it’s important to consider your engine setup. If your build focuses on low-end torque and daily driving comfort, the gains may not be as noticeable at lower RPMs.
4. Engine Bay Clearance:
   • Depending on your vehicle, you might need to check for engine bay clearance issues. Some setups may require modification or relocation of certain components like the brake booster or coolant lines.

Installation Overview

1. Tools Needed:
   • Standard hand tools (sockets, wrenches)
   • Torque wrench
   • Gasket scraper (if needed)
2. Steps:
   • Disconnect battery and remove any components that block access to the intake manifold, such as the intake system and throttle body.
   • Drain the coolant if necessary, as some intake manifolds have coolant passages.
   • Remove the old intake manifold by unbolting it from the cylinder head and disconnecting any sensors or hoses.
   • Install the new Skunk2 manifold, making sure to use a new intake manifold gasket for a proper seal.
   • Reconnect all sensors, hoses, and throttle body components.
   • Refill the coolant and check for any leaks or clearance issues.
   • If possible, perform a baseline tune after installation.

Popular Models for Skunk2 Pro Series Manifold

• Skunk2 Pro Series for B16/B18: Perfect for VTEC engines, especially popular with Integra Type R (DC2) and Civic builds.
• Skunk2 Pro Series for K20/K24: Ideal for RSX Type S, Civic Si (EP3/FG2), and other K-series engine swaps.

Conclusion

The Skunk2 Pro Series Intake Manifold is a high-performance, race-proven upgrade for Honda and Acura engines. It enhances airflow, particularly in the upper RPM range, which translates to noticeable gains in horsepower and throttle response. It’s a great addition for anyone looking to maximize the performance of their build, whether it’s for street use, track days, or competitive racing.
