Mishimoto

Mishimoto parts in this range suit Subaru WRX and STI (oil cooler kits and silicone hose kits for VA and VB chassis), Toyota GR86 and 86 and Subaru BRZ (thermostatic oil coolers and tow hooks), Toyota GR Corolla (intercooler kits) and Mitsubishi Lancer Evolution X (BOV return hoses). Fitment varies by generation and engine code, so check each kit description against your car before ordering.

• Oil coolers and oil cooler kits (standard and thermostatic)
• Intercooler kits (front mount and top mount)
• Silicone hose kits (radiator, coolant, BOV return)
• Expansion tanks and overflow tanks
• Radiators and radiator hose kits
• Tow hooks

Mishimoto kits are designed for specific platforms rather than as universal parts. An oil cooler on a WRX or STI helps keep oil temperatures in check under sustained load, such as spirited driving or a day on track. The thermostatic oil cooler for BRZ and 86 only brings the cooler online once oil reaches temperature, so the engine isn't overcooled on cold starts. Silicone hose kits replace factory rubber hoses, which can perish with age and heat cycling, and the GR Corolla intercooler kit adds core capacity for cars running more boost than the factory core was designed for.

Most Mishimoto kits are direct replacements, but some intercooler and oil cooler kits need minor trimming of factory bumper supports or brackets depending on model year. If you're running a JDM import or a variant with different bumper supports, check clearances before ordering. For the Evo X BOV return hose, check against your factory routing, especially if you already have aftermarket piping.

Installation by a professional is recommended. Cooling system work needs fresh coolant or oil of the correct specification and a proper bleed procedure, and some intercooler kits require bumper removal.

Will a Mishimoto oil cooler kit need tuning changes on my WRX or STI?
Oil cooler kits generally don't require a retune. Intercooler upgrades that change airflow can benefit from a tune, so check with your tuner.

What's the difference between the standard and thermostatic oil cooler for BRZ/86?
The thermostatic version only routes oil through the cooler once it reaches operating temperature, so the engine warms up normally. The standard cooler runs oil through it all the time.

Do these kits suit street cars or only track builds?
Both. Many are used on daily-driven cars purely for reliability and heat management.
