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.

Fitment FAQ
Will this part fit my specific model and year?
This intake manifold is intended for Direct replacement for Yamaha 400cc and 600cc air-cooled engines. Please verify your OEM cross-reference codes.; Fitment Years; Replaces OEM Part #; Yamaha; XJ600S Diversion; 1992 – 2002; 4BR-13598-10 / 4EB-13598-00. Listed year information includes 1992–2002, 1994–2002, 1992–1993, 1992, 2002. It is best matched to original part number(s) 4BR-13598-10, 4EB-13598-00. Key physical/spec details from the product data include Height: 24mm (0.94"), Inner Diameter: 35mm (1.37"), 400cc. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. Match your original part number to 4BR-13598-10, 4EB-13598-00 before purchase. For this intake manifold, also compare the bolt spacing, intake port shape, carb-side inner diameter, vacuum nipple position, and gasket shape. This is especially important for Yamaha XJ600S/XJ600N/XJ400 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this intake manifold for machines outside the listed compatibility, or for units with different port shapes, bolt spacing, carb-side diameter, or vacuum nipple locations. If your original part number does not cross-reference with 4BR-13598-10, 4EB-13598-00, treat the fitment as unconfirmed. Model years outside 1992–2002, 1994–2002, 1992–1993, 1992, 2002 should be verified separately. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the bolt spacing, intake port shape, carb-side inner diameter, vacuum nipple position, and gasket shape. Confirm OEM/cross-reference number(s): 4BR-13598-10, 4EB-13598-00. Recheck listed specs such as Height: 24mm (0.94"), Inner Diameter: 35mm (1.37"), 400cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
