S&S Intake Manifold 55mm for M8

The factory Milwaukee-Eight comes with a plastic intake manifold — and that’s a problem. While it keeps costs down, it also brings heat soak, warping issues, and long-term durability concerns. Plastic becomes brittle over time, especially in hot environments or under performance pressure.

If you're running a tuned engine, stage kits, or just riding hard, that plastic manifold becomes a serious bottleneck. It restricts airflow, limits throttle response, and can even cause vacuum leaks when it starts to deform.

Upgrading to a performance aluminum intake manifold means better airflow, cooler operation, and rock-solid reliability — not to mention a cleaner, more aggressive look. If you’re serious about performance, it’s one of the smartest upgrades you can make.

You have two options to pick from:

• 55mm CNC intake manifold (raw finish)
• 55mm CNC ported intake manifold for even better airflow(black coated)
