⚙️ Eliminate Intake Leaks – Upgrade Idle Stability & Throttle Smoothness
The OffRamp CNC-machined aluminum intake manifold is a direct upgrade over the stock plastic/rubber manifold found on Milwaukee-Eight engines. Designed to solve common air leakage issues caused by OEM material fatigue, this precision part restores proper air delivery, idle smoothness, and throttle response.
