Internal fins
Internal fins carry heat from the oil, coolant or charge air into the metal of the core. Consistent fins give you consistent cooling across the whole block.
Premium aluminum core material
Built bar and plate. Finished fast.
The aftermarket's only true bar and plate aluminum core for radiators, oil coolers and charge air coolers, with thousands of finished cores in stock and ready to ship.
The construction
Why bar and plate
Flat plates and formed fins are stacked, the edges are sealed with solid aluminum bars, and the whole stack is brazed into a single block. It is a different build from a tube and fin radiator.
- Solid edge bars
- Bars close off the sides of each layer, so the core is a rigid block instead of a bundle of tubes.
- Fins in every layer
- Formed fins sit between each pair of plates, inside and out, to move heat where it needs to go.
- One brazed block
- The stack is brazed as a unit, giving oil, water and charge air cores the same basic construction.
Fin quality
Better fins, inside and out
Alumi-Core cores are built with higher quality internal and external fins than other aluminum cores on the market.
External fins
External fins pass that heat into the airstream. An even fin pattern across the face keeps the core working the same from edge to edge.
