55mm Performance Intake Manifold for Harley M8 Softail & Touring 2017–Later

⚙️Eliminate Intake Leaks – Improve Idle Stability & Throttle Smoothness

The OFFRAMP aluminum intake manifold is a direct upgrade over the stock plastic and rubber intake manifold used on Milwaukee-Eight engines.

Engineered to address common air leak issues caused by OEM material fatigue and deformation, this intake manifold helps restore consistent airflow, resulting in smoother idle performance and improved throttle response. Its rigid aluminum construction provides a more reliable seal under heat and engine vibration, making it an ideal solution for both daily riding and performance-oriented builds.

✅Key Features

• Material: High-strength aluminum construction for improved durability and heat resistance
• Diameter: 55mm
• Sealing: Includes 3 high-temperature O-rings for reliable and consistent sealing
• Performance Benefits: Helps eliminate intake air leaks that can cause rough idle and throttle hesitation
• Finish: Black
• Installation: Direct bolt-on installation; no ECU tuning required for stock applications

💡 Why Upgrade?

• OEM intake manifolds often degrade over time, leading to vacuum leaks
• Leaking manifolds cause poor idle, misfires, or jerky throttle
• This Precision billet alternative guarantees long-term reliability and consistent airflow

📦 What’s in the Box

• 1 × OffRamp CNC intake manifold
• 3 × Sealing O-rings (high-temp rated)
• Mounting hardware (optional, based on variant)

📌 Notes

• ✔ Compatible with all Milwaukee-Eight (M8) engines from 2017 to 2024
• 🔧 Professional installation recommended for optimal sealing
• 🧾 Available in standard and performance-tuned variants

Restore power, smoothness, and reliability
