The Suzuki part number 13655-87J01 is the genuine OEM Inlet Air Temperature Sensor Grommet. It is the rubber mounting seal directly paired with the 13650-52G00 IAT Sensor.

Function & Location

• Purpose: Provides an airtight, vibration-dampening rubber seal around the air temperature sensor tip.
• Placement: It presses directly into the engine's plastic intake manifold or silencer box assembly, allowing the tip of the sensor to securely protrude into the moving airstream without leaking vacuum.

Application Details

• Primary Use: Most commonly referenced in Suzuki 4-stroke outboard marine engines such as the DF40, DF50, DF115, DF140, and DF225 series.
• Interchange: This part supersedes or replaces older Suzuki part number 13655-87J00.

Cross-References & Equivalent Parts

Replaces OEM 5031393. The 13655-87J01 Grommet (Air Temp) is equivalent to:

• 5031393 – Evinrude / Johnson / OMC / BRP

When to Replace It

It is highly recommended to replace this inexpensive grommet alongside a new sensor if the current rubber is brittle, cracked, stretched out, or coated in engine oil residue, as a faulty seal can introduce unmetered air (vacuum leaks) into the intake system.
