• Engine or transmission: Check whether the cooler is designed for engine oil or for gearbox fluid. Transmission coolers are listed against specific gearboxes, such as the ZF8 automatic or a Subaru CVT.
• Chassis and engine codes: Match the chassis code (for example VA, VB, ZC6, ZD8, FK8, G87) and the engine code (for example B58, EA888.3, G16E-GTS) shown in the product title.
• Model conditions: Some kits are limited to particular variants. For example, one PERRIN CVT cooler kit for the Subaru WRX (VBH) suits the base model only. Always read the fitment note on each listing.
• Kit type: PERRIN offers full kits, tuner kits and relocate kits for several Subaru and Toyota models. Compare what each listing includes before you choose.
• Universal core size: Koyorad cores are listed by row count and dimensions, from the 10 row (286x76x51mm) to the 35 row (286x279x51mm). Several of these cores use -10AN ORB ports, so confirm the core fits your mounting space and your fittings.
• Thermostatic or non-thermostatic: Mishimoto sandwich plates for the Subaru BRZ (ZC6) / Toyota 86 (ZN6) come in thermostatic (gold) and non-thermostatic (silver) versions.

Fitting an oil cooler involves draining and refilling oil or transmission fluid, mounting the core and routing the lines correctly. A universal core also needs compatible lines, fittings and a sandwich plate or adapter, so plan the complete setup before you buy. If you are adding gauges, the PERRIN oil temperature and pressure adapter provides sender ports on supported Subaru and Toyota models. Replacement O-rings are available in the PERRIN O-ring kit.

Note: Check the fitment conditions on each listing. Installation by a professional is recommended.

What is the difference between an engine oil cooler and a transmission cooler?

An engine oil cooler cools the engine's lubricating oil, while a transmission cooler cools the gearbox fluid, such as in a ZF8 automatic or a Subaru CVT. The product title confirms which system each cooler is designed for.

What does the row count on a universal oil cooler mean?

The row count is the number of rows in the cooler core, and more rows means a larger core. For example, the Koyorad 10 row core measures 286x76x51mm and the 35 row core measures 286x279x51mm.

What is a thermostatic sandwich plate?

It is an adapter that fits at the oil filter mount and includes a thermostat designed to send oil to the cooler once it has warmed up. Mishimoto offers thermostatic and non-thermostatic versions for the Subaru BRZ (ZC6) and Toyota 86 (ZN6).

Can I install an oil cooler kit myself?

Installation by a professional is recommended, because it involves draining and refilling fluids and routing lines correctly. Contact our team if you need help confirming which kit suits your vehicle.
