Mishimoto Thermostatic Oil Cooler Kit Black Fiesta ST 14-16

The Mishimoto thermostatic oil cooler kit for the Fiesta ST 2014–2016 controls engine oil temperature to improve reliability under high-stress, turbocharged operation such as track sessions or aggressive street driving.

Turbocharged 4-cylinder engines like the 1.6L EcoBoost in the Fiesta ST can overheat their oil quickly within a few laps or during sustained hard use; this kit addresses that thermal risk by adding a dedicated, thermostatically managed oil cooling solution designed for repeatable performance and reduced thermal degradation of engine oil.

• Thermostatic oil cooler kit — thermostatic regulation helps maintain optimal oil temperature during varied operating conditions, reducing the risk of oil overheating during sustained high-load use.
• Vehicle-specific fit — engineered for the Fiesta ST (2014–2016) to ensure proper routing and integration with the 1.6L EcoBoost platform, minimizing installation compromises and fitment issues.
• Black finish — durable cosmetic finish suitable for under-hood environments while maintaining a clean, factory-integrated appearance.
• Mishimoto engineering and support — designed and validated by Mishimoto, a supplier known for motorsports-grade cooling components to provide consistent thermal management under elevated operating stresses.

This kit is intended for turbocharged applications where sustained oil temperatures can exceed safe operating thresholds during track use or aggressive driving. By adding a thermostatic oil cooler, the system helps protect oil viscosity and component longevity, supporting consistent lubrication performance under high thermal loads.

Installation considerations: the kit is vehicle-specific and intended to integrate with the existing oil and cooling interfaces on the Fiesta ST 2014–2016. Follow Mishimoto installation instructions and recommended service intervals to ensure reliable operation and leak-free connections.
