🔧 Product Description

Genuine Used Suzuki Johnson DF90-DF140 Air Silencer Duct - Part Numbers: 13840-90J00 and 5033696

A genuine pre-owned intake-air duct for selected Suzuki four-stroke outboards and Suzuki-manufactured Johnson four-stroke engines.

Suzuki part number 13840-90J00 and Johnson/BRP part number 5033696 identify the same OEM silencer duct.

The duct attaches to the main air-silencer assembly and directs incoming air into the silencer chamber while helping reduce intake noise and shield the intake from direct spray.
