Description
The Mishimoto MMOC-U34BK is a complete, universal-fit oil cooler kit built around Mishimoto’s proven 34-row stacked-plate cooler core, finished in black anodized aluminum. This particular kit ships as the Black, Non-Thermostatic configuration and pairs the cooler core with a billet anodized aluminum sandwich plate, pre-assembled stainless steel braided oil lines, and the fittings needed to adapt it to most engine bays. Whether you’re cooling a boosted rotary or a blown small block, this Mishimoto oil cooler kit is built to lower oil temperatures without adding unnecessary pressure loss.
Proper oil temperature regulation extends and preserves the life of a stock or high-performance engine, and this Mishimoto oil cooler kit gives builders the core components needed to add that protection. The 34-row bar-and-plate core is designed to withstand high fluid pressures while significantly reducing oil temperatures, and the included sandwich plate mounts to route oil through the cooler. Because the kit includes both a -16 and M20-1.5 sandwich plate adapter, this Mishimoto cooler supports installation across most makes and models, making it a genuinely universal cooling solution for engine swaps, track builds, and performance applications alike.
Vehicle Applications
As a universal oil cooler kit, the Mishimoto MMOC-U34BK is not limited to a single make or model. It’s designed to bolt into most vehicles thanks to the included -16 and M20-1.5 sandwich plate adapters, which cover common oil filter thread sizes. Mishimoto notes this kit is suited for a wide range of builds, from boosted rotary engines to blown small block engines, giving enthusiasts a single kit that can be adapted to whatever platform they’re working with.
