FL350 Intake Manifold for Stock Carb

Permanent, Leak-Proof Intake Manifold Solution for the FL350R

On the 1985 Honda Odyssey FL350R, the original vulcanized rubber intake manifold is one of the highest-risk failure points on the entire machine. Decades of heat cycles, heavy engine vibration, and fuel exposure leave factory rubber brittle, warped, and covered in hairline dry-rot cracks. Under engine load, these cracks open up and draw in unmetered air—creating an instant lean condition that can easily melt a piston and seize your two-stroke top end.

Because brand-new OEM intake boots have been discontinued for years, finding a dependable replacement that guarantees an airtight seal can be nearly impossible. Our replacement intake manifold delivers a rugged, modern overhaul engineered specifically for the stock 32mm carburetor, pairing a chemical-resistant 3D-printed body with a heavy-duty stainless steel retention bracket to protect your engine from catastrophic air leaks.

Engineered Construction & Stainless Steel Retention

Unlike basic rubber boots that distort and pull away under clamping torque, this manifold is built for long-term mechanical stability:

• Advanced Fuel-Resistant Polymer: 3D-printed from a tough, high-temperature engineering polymer selected specifically for its resistance to fuel vapors, premix oils, ozone, and continuous engine heat.
• Laser-Cut Stainless Retention Bracket: Includes a heavy-duty stainless steel retention plate that sandwiches the mounting flange flat against the reed cage. This distributes bolt torque uniformly across the entire gasket face, eliminating flange distortion and preventing the manifold from flexing or cracking under rough riding conditions.
• Smooth Internal Transition: Designed with clean internal geometry to provide a smooth, turbulence-free path from the carburetor spigot directly into the engine's reed block.

Key Features & Benefits:

• Direct OEM Fit: Designed to mount your original 32mm carburetor cleanly without cutting, drilling, or frame interference.
• Positive Clamping Seal: Eliminates dangerous lean-running intake air leaks, ensuring stable jetting, reliable idle, and engine protection.
• Versatile Reed Compatibility: Works seamlessly with stock FL350 reed cages (including setups using an optional reed stuffer) and aftermarket 1988 CR250R V-Force 3 reed blocks.
• Chassis Clearance: Sits cleanly within the factory frame rails and roll cage tubing for easy carburetor access and maintenance.

What's Included:

• 1x High-Performance 3D-Printed Intake Manifold (Stock 32mm Carb Spigot Fitment)
• 1x Heavy-Duty Stainless Steel Retention Bracket
• Mounting hardware and heavy-duty carburetor spigot clamp

Note: Carburetor, reed cage, reed gaskets, and rear airbox elbow are not included.
