Mishimoto offer this Dual Pass version of their Universal Oil Cooler Bar primarily for track use.Utilising a dual-pass design with a sturdy bar-and-plate core this is a serious bit of kit.Dual-pass means the oil passes both ways through the cooler. While this can lead to slower flow, it also maximises heat dissipation.A bar-and-plate core is typically a bit heavier than a tube-and-fin core, but can offer better cooling when the vehicle is stationary. It's also more durable to stone impacts to the front of the vehicle.This is a serious bit of kit for serious use.As with most things Mishimoto make, this is constructed from 6061 Aluminium.The unit is 6.30" high, 17.01" long, by 1.57" wide. The core itself is 13.98" x 5.51" x 1.57".Fittings are -10AN.
