Laminova A43-330K Oil Cooler Build Kit — 330mm Core, Choice of Fittings

The Laminova A43-330K is the bare-build kit for the 330mm-core C43 oil cooler: core, housing, seals/gaskets, and hardware — without oil or water fittings pre-installed, so you can configure exactly the connections your build needs. Select your water and oil fitting size above and we’ll include the matching fittings assembled to the housing before it ships.

The Laminova core uses a laminar-flow, solder-free extruded aluminum design: coolant and oil are separated by an almost infinite series of interlocking laminar fins (0.2mm thick, 0.3mm oil flow gap), keeping oil flow laminar for high heat transfer with very low pressure drop. A 330mm Laminova core performs similarly to a typical 25–30 row air-to-air cooler, in a fraction of the space.

• 330mm core, ~16.00" overall body length, ~2.7" housing diameter
• Extruded aluminum construction (EN-AW-1050A, 99.5% aluminum)
• O-ring sealed, solder-free modular housing — disassembles for cleaning/service
• Choice of push-on hose barb or thread-on AN water connections; choice of AN oil connections
• Includes core, housing, all seals/gaskets, and mounting hardware

Ideal for engine oil, transmission, or power steering cooling in road racing and other motorsport applications, and equally well suited to robotics, drone, experimental/light aircraft, marine, and light industrial fluid-cooling systems needing maximum cooling capacity.
