Yamaha - Reed Set - Air Intake Component - 6J8-W0004-00-00

Overview

The Yamaha Reed Set | 6J8-W0004-00-00 is one of those parts that makes a noticeable difference in how your engine runs, even though you don’t see it. When reeds start to wear or chip, you’ll feel it in rough idle, poor throttle response, or that sluggish pickup. These sit right at the intake and control how air flows into the engine, so they need to seal clean every cycle. Swapping in a fresh set is a solid way to bring your motor back to life without chasing bigger problems.

Key Features

• Controlled Air Intake Flow – Regulates airflow into the engine for proper combustion.

• Crisp Throttle Response – Helps restore smooth acceleration and engine responsiveness.

• OEM Fit Design – Built to match Yamaha reed cages for proper sealing and alignment.

• Durable Reed Material – Designed to handle constant flexing without cracking or fatigue.

Compatibility

Compatible with select Yamaha outboard engines using this reed set configuration.
