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 Carburetor Compatibility 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. PZ30 Designed Carburetor Model Flange Carburetor Connection Type CNC Precision-Machined Adapter Engine Compatibility 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 Predator Engines Predator 301cc (8 HP) Predator 420cc (13 HP) HONDA GX SERIES Honda Engines Honda GX240 Honda GX270 Honda GX340 Honda GX390 BRIGGS & STRATTON 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. Flange Mounting Design 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-SIDE MOUNTING 52 mm Engine Flange Hole Spacing Engine-side flange mounting hole center-to-center spacing for compatible engine intake configurations. CARBURETOR-SIDE MOUNTING 48 mm Carburetor Flange Hole Spacing Reference carburetor-side flange mounting spacing for the intended NIBBI PZ30 connection. Verify dimensions before ordering. Fitment Reminder: Mounting hole spacing refers to the center-to-center distance between bolt holes, not the individual bolt hole diameter. Please compare both flange patterns and the intake opening with your existing components. Practical Engine Upgrades 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 Installation Overview 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. 01 Prepare the Engine Remove the original intake component if required. Clean and inspect the engine mounting surface, and verify the bolt hole alignment. 02 Mount the Adapter Position the intake manifold using the correct gasket and mounting hardware. Tighten the fasteners according to the engine manufacturer's requirements. 03 Connect & Inspect Attach the compatible flange carburetor. Check all mating surfaces for secure sealing, verify throttle movement, and inspect for intake leaks before operation.

Confirm Engine Compatibility Identify your exact Predator, Honda GX, or Briggs engine model and verify the intake mounting configuration. 2. Measure Flange Hole Spacing Compare the mounting hole center-to-center distances with your original intake system. The engine-side reference spacing is 52 mm. 3. Check Carburetor Fitment Designed for the NIBBI PZ30 flange-mount carburetor. Verify the carburetor-side mounting pattern and intake dimensions. 4. Verify Installation Clearance Ensure enough space for the carburetor, air filter, throttle cable, and surrounding engine components. Installation Note: Proper gasket sealing, correct mounting hardware, and secure installation are essential for reliable operation. Inspect the intake system for air leaks, verify proper throttle movement, and confirm carburetor tuning before operating the engine. Professional installation is recommended for modified engine setups.
