FLANGE INTAKE MANIFOLD
PRECISION FIT. SMOOTHER FLOW.
Upgrade your engine's intake connection with the NIBBI Racing Flange Intake Manifold Adapter Kit. Precision CNC-machined from high-strength aluminum alloy, this manifold is designed to connect compatible Predator, Honda GX, and Briggs engines with the NIBBI PZ30 flange-mount carburetor.
Featuring a smooth internal passage, carefully machined mounting surfaces, and a corrosion-resistant black anodized finish, it provides a dependable foundation for your engine's intake system.
Built for a Better Intake Connection
The intake manifold plays an important role in delivering the combustible air-fuel mixture from the carburetor to the engine. A properly designed manifold helps maintain smooth flow and a secure connection between these essential components.
Smooth Intake Passage
Precision-machined internal surfaces help minimize unnecessary intake resistance and support smooth delivery of the air-fuel mixture into the engine.
Secure Flange Mounting
Designed for compatible flange-mounted carburetors, the manifold provides a stable mounting interface with properly matched hardware and gaskets.
CNC Aluminum Construction
Manufactured from durable aluminum alloy with a black anodized finish for corrosion resistance, strength, and long-term service in demanding engine environments.
Machined for Strength.
Designed for Flow.
The NIBBI Flange Intake Manifold is crafted from solid aluminum alloy using precision CNC machining technology.
Its smooth internal channel is designed to reduce unnecessary flow resistance, while the machined mating surfaces help support reliable sealing when correctly installed.
The black anodized surface adds corrosion resistance and complements performance engine builds with a clean, professional appearance.
Built for Demanding Applications
- ✓ High-strength billet aluminum construction
- ✓ Precision CNC-machined mounting surfaces
- ✓ Smooth internal intake passage design
- ✓ Durable black anodized protective finish
- ✓ Corrosion-resistant aluminum alloy body
- ✓ Designed for a secure, properly sealed connection
DESIGNED FOR NIBBI PZ30.
This flange intake manifold is designed for use with the NIBBI PZ30 carburetor, providing a matching flange-style mounting connection for compatible engine applications.
Unlike spigot-mounted intake systems that use a rubber coupling, the flange-style interface provides a bolted connection between the carburetor and manifold. Proper gasket sealing and mounting alignment are essential for reliable operation.
Compatible with Popular Small-Engine Platforms
Designed for selected Predator, Honda GX-Series, and Briggs & Stratton engines, this manifold adapter supports compatible carburetor upgrade and replacement projects on a variety of small-engine applications.
Predator Engines
- Predator 301cc (8 HP)
- Predator 420cc (13 HP)
Honda Engines
- Honda GX240
- Honda GX270
- Honda GX340
- Honda GX390
Briggs Engines
- Briggs 1450 Series
- 305cc Engine
Note: Engine compatibility is subject to the specific intake flange configuration and mounting dimensions. Please compare your existing intake system before purchasing.
Precise Mounting. Dependable Sealing.
The flange mounting design helps create a secure mechanical connection between the engine, intake manifold, and compatible carburetor. Correct mounting dimensions and gasket sealing help prevent unwanted air entering the intake system.
Engine Flange Hole Spacing
Engine-side flange mounting hole center-to-center spacing for compatible engine intake configurations.
Carburetor Flange Hole Spacing
Reference carburetor-side flange mounting spacing for the intended NIBBI PZ30 connection. Verify dimensions before ordering.
A Dependable Foundation for Your Intake Setup.
Whether you're replacing an old intake manifold or building a customized carburetor setup, a reliable intake connection is an important part of engine performance.
The NIBBI flange manifold is designed to support a proper connection between compatible engines and the PZ30 carburetor while maintaining a compact, rigid mounting structure.
Its lightweight aluminum construction makes it a practical option for go-karts, mini bikes, and other compatible small-engine projects.
Suitable Applications
- ✓ Go-Kart Engine Builds
- ✓ Mini Bike Modifications
- ✓ Carburetor Replacement Projects
- ✓ Custom Intake System Installations
- ✓ Compatible Small-Engine Equipment
Straightforward Installation with Proper Fitment
The flange-style manifold is designed for installation on compatible engine mounting patterns. Before installation, confirm that the carburetor and engine flange dimensions match the adapter.
