Mishimoto

Mishimoto cooling parts in this range suit Subaru WRX and STI (including oil cooler kits and silicone hose kits for the 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 the specific kit description against your build before ordering.

Mishimoto builds specifically for the platforms we sell into, not generic universal kits with a lot of guesswork in the install. A Mishimoto oil cooler on a WRX or an oil cooler kit on an STI is there to keep oil temps in check once you're doing more than commuting, whether that's a spirited weekend drive or a full day on track. The thermostatic oil cooler option for BRZ and 86 only brings the cooler online once the oil's up to temp, so you're not overcooling on a cold morning drive. We've sold plenty of their silicone hose kits to daily-driven WRXs where the factory rubber was starting to perish, and the difference in reliability over a few Australian summers is real. On the GR Corolla side, the intercooler kit is one of the first upgrades we recommend once a car's making more boost than the factory core was designed for.

Most Mishimoto kits are designed as direct bolt-on replacements, but some intercooler kits and oil cooler kits need minor trimming of factory bumper supports or brackets depending on your model year. AU-delivered cars are generally covered in the kit descriptions, but if you're running a JDM import or a variant with different bumper supports, double check clearances before you order. Radiator hose kits and expansion tanks are usually the easiest install in the range and a good starting point if you're new to fitting your own cooling gear. Tow hooks for BRZ, 86 and GR86 are a straight bolt-in and one of the quickest jobs on this page. The BOV return hose for Evo X is a simple swap but worth checking against your factory routing before you order, especially if you've already got aftermarket piping.

Will a Mishimoto oil cooler kit fit my WRX or STI without tuning changes?
Most oil cooler kits are a straightforward addition and don't require a retune. Intercooler upgrades that significantly change airflow can benefit from a tune, so check with us if you're unsure.

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's reached operating temperature, so the engine warms up normally on cold starts. The standard cooler runs oil through it all the time.

Do these kits suit street cars or only track builds?
Both. A lot of our customers run these on daily-driven cars purely for reliability and heat management, not just outright track performance.

Can I fit a Mishimoto intercooler kit or silicone hose kit myself?
Most kits are DIY-friendly with basic hand tools, though some intercooler kits involve bumper removal. If you're not confident, we can point you to a workshop that's fitted these before.

Does Mishimoto cooling gear come with a warranty?
Yes, Mishimoto covers its products under manufacturer warranty. Reach out to us if you need help with a claim.
