The factory N55 intake manifold becomes a limiting factor once power levels exceed 400whp. The ARM N55 Intake Manifold eliminates this bottleneck with increased plenum volume, optimized high-flow runners, and durable aluminum construction that resists heat soak, cracking, and deformation.

This manifold supports port injection for builds requiring higher fueling capacity, including full E85, big turbo upgrades, or methanol-free tuning at 600+whp. For setups not requiring additional fueling, block-off plugs are included for easy installation.

Construction

Built from high-strength T6061 aluminum, the ARM N55 Intake Manifold installs using all factory connections for simple OEM-style fitment. No cutting, fabrication, or wiring extensions are required. The manifold features:

• Full aluminum construction
• Smooth, high-flow runners
• Optimized plenum volume
• Machined DME mounting flange
• Integrated top-mount port-injection bungs
• Multiple expansion vacuum ports for accessories such as blow-off valves, boost gauges, and Hobb’s switches
