13 Plate Remote Cooler Assembly

This multi plate design oil cooler assembly is used in virtually every severe duty type of oil cooling environment found today. Recognized by Mercury Racing and every high profile professional engine builder as the most effective method to control oil temperature. The 8, 13, and plate oil cooler design offers maximum heat dissipation in the most compact size and use of space. This is basically the same cooler package that's incorporated into a dual cooler style of race bellhousing. Now you can have the same great cooling features in a remote mountable unit. The cast aluminum housing features a hard anodized finish for corrosion resistance. Each housing has 1" NPT water inlets/outlets and a dual bolt mounting flange and will accept a 8, or 13 plate cooler assembly when used with the appropriate cover assembly.

Length 11-3/4", Height 5", and depth based on the 13 plate configuration is 5-3/4".
