Intake Manifold Pipe Set (4pcs) for Yamaha XJ600S Diversion, XJ600N, XJ400 | OEM 4BR-13598-10

Product Overview

Restore the smooth, dependable performance of your Yamaha inline-four with the GOOFIT Heavy-Duty Intake Manifold Set. Specifically engineered for the XJ600S Diversion, XJ600N, and XJ400, this 4-piece kit is a precision replacement for OEM #4BR-13598-10 and #4EB-13598-00.

As a robust air-cooled engine, the Yamaha XJ series generates significant cylinder head heat. Over years of service, the original intake boots inevitably harden and crack, allowing "unmetered air" to enter the engine. This leads to the common "hanging idle" issue and lean-running conditions. Our upgraded manifolds feature a thickened pipe wall design for superior shock absorption and a permanent vacuum seal, ensuring your engine idles perfectly and responds crisply to every throttle input.

Product Compatibility

Direct replacement for Yamaha 400cc and 600cc air-cooled engines. Please verify your OEM cross-reference codes.

Key Features

• Thickened Wall Construction: Unlike standard replacements, these manifolds feature a reinforced pipe wall. This added thickness provides exceptional shock absorption, dampening engine vibrations that can cause fuel foaming in the carburetors.
• Airtight Vacuum Sealing: Engineered to the exact 35mm internal diameter required for XJ600 carburetors. This ensures a 100% vacuum-tight connection, fixing common issues like "hunting idles" and backfiring on deceleration.
• Superior Corrosion Resistance: Made from high-grade materials that resist the degrading effects of modern fuels and engine oils. The boots remain flexible and crack-free even after extended exposure to the intense heat of an air-cooled engine.
• Restores Engine Smoothness: By providing a stable, turbulence-free intake path, these manifolds improve combustion efficiency, directly enhancing fuel economy and power output.
• Complete 4-Piece Kit: Sold as a full set for all four cylinders. Replacing all boots simultaneously is the only way to ensure perfect carburetor synchronization and balanced performance across the entire engine.
