Oil Cooler Non Thermostatic Black Fits 14-16 Fiesta ST

Oil cooler non-thermostatic for 2014–2016 Fiesta ST designed to reduce rapid oil overheating during track sessions and aggressive street driving, addressing the high oil-temperature risk inherent to turbocharged 1.6L EcoBoost engines.

Turbocharged, high-stress 4-cylinder engines like the 1.6L EcoBoost in the Fiesta ST can overheat their oil very quickly within a few laps on the track or aggressive street driving. Even with the stock liquid-to-liquid heat exchanger, the engine can still run very hot and run the risk of oil degradation and reduced component longevity.

Purpose-built design — This non-thermostatic oil cooler is intended to provide a dedicated path for oil cooling under sustained high-load conditions, helping to manage oil temperatures that the factory system may not control effectively during extended track use.

Application note — Engineered for use on 2014–2016 Ford Fiesta ST models equipped with the 1.6L EcoBoost, providing a targeted cooling solution where rapid oil temperature rise is a documented concern.

Brand assurance — Provided by Mishimoto, a brand recognized for motorsports-focused cooling components and endurance testing to support demanding driving conditions.

Technical considerations

• Non-thermostatic operation — Eliminates thermostat control to prioritize direct oil cooling during sustained high-load events.
• Dedicated oil cooling path — Intended to supplement the factory liquid-to-liquid heat exchanger when prolonged track or aggressive driving causes elevated oil temperatures.
• Vehicle-specific fitment — Designed to fit 2014–2016 Fiesta ST platforms with the 1.6L EcoBoost engine architecture.

Maintenance and performance impact — By addressing oil temperature management, this oil cooler helps reduce the risk of oil breakdown and maintains lubricant effectiveness during repeated high-load cycles, contributing to more consistent engine performance and component reliability.
