Mishimoto Water Temp. Sensor Adapter 38mm Black – Universal Fit
The Mishimoto water temperature sensor adapter installs directly into 38mm inner diameter radiator hoses on a wide range of performance vehicles including Honda Civic, Acura Integra, Subaru Impreza, and Nissan models. It positions the sensor in the direct flow path to the radiator for the most precise coolant temperature measurements available. This setup delivers real-time data to help monitor engine health and avoid overheating during demanding drives.
Key Features
- Aluminum Construction: CNC-machined from billet aluminum for strength and resistance to corrosion in high-heat coolant environments
- 1/8″ NPT Bung: Threads securely hold standard water temperature sensors for reliable signal transmission without leaks
- 38mm Hose Clamp Design: Clamps firmly between cut hose sections to maintain hose integrity and flow rates
- Black Anodized Finish: Provides a durable powder-coated look that resists chipping and complements engine bay aesthetics
- Direct Flow Placement: Ensures sensor reads actual coolant temperature heading to radiator unlike stock port locations
Product Notes
- Verify radiator hose inner diameter measures exactly 38mm before purchase
- Pair with 1/8″ NPT water temperature sensors and aftermarket gauges for full data acquisition setup
- Handle with care during install to avoid scratching anodized surface
Installation Notes
- Professional installation recommended.
