      -VAC  E46 M3 Oil Cooler-
    Design & Layout Despite an external size not much larger than OE, internal volume and overall core size is hugely increased to nearly twice of OE. Twin Pass cores are literally a dual-oil-cooler in-1 offering the most ideal way to cool the oil in the smallest space.

    With a slight amount of trimming to the OE plastic cooler shroud, this cooler is a direct bolt in replacement and no other mods are necessary. It even directly bolts to the stock lines.

    Core type & Construction Internal "Wave Pattern Core" design offers a dramatic increase in surface area for cooling potential, allowing oil to flow easily yet coming into contact with much heat exchanger surface for dramatic improvements vs. standard core types.

    High strength welds and core materials offer long life, resistance to damage from road debris and failures associated with high oil pressures and cold starts.

    Just like nearly all of our VAC parts, The entirety of the oil cooler is made in the USA

    Capacity Nearly double that of the OE cooler without a large increase in size
