Product Overview
Refresh the heartbeat of your classic inline-four with the GOOFIT 4-Piece Intake Manifold Boot Set. Specifically engineered for the Yamaha XJ900 (1983-1984) and the later XJ900F (1991-1994), this kit is the essential solution for aging, cracked, or hardened intake boots.
On vintage air-cooled engines like the XJ900, the rubber manifolds are exposed to extreme cylinder head heat. Over time, these parts develop vacuum leaks that lead to "hunting" idles, engine hesitation, and difficult cold starts. Our high-quality replacements are designed to handle high-pressure environments, ensuring your engine breathes clean, metered air for a smoother, more powerful ride.
Product Compatibility
Direct replacement for the Yamaha XJ900 series. Please verify your production year and engine configuration.

If your original part number does not cross-reference with 1983-1994, 1983-1984, 1991-1994, treat the fitment as unconfirmed. Model years outside 1983–1994, 1983–1984, 1991–1994, 1983, 1994 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.
