Oil Cooler Flange Mount -10AN

The Oil Cooler Flange Mount -10AN from Allstar Performance is a precision-engineered adapter designed for serious engine builders and high-performance enthusiasts who demand reliable thermal management in competition and street applications. This flange mount solution addresses a critical cooling need: maintaining optimal oil temperature under sustained load, which directly impacts engine longevity, oil viscosity stability, and overall performance consistency. Whether you're running a naturally aspirated buildup or a forced-induction platform, proper oil cooling separates marginal setups from bulletproof powerplants.

Built with the -10AN port standard, this flange mount accommodates industry-standard AN hose fittings and provides a secure, leak-free interface for oil cooler lines in tight engine bays. The flange design distributes load evenly across the block or mounting surface, reducing stress concentration points that can lead to weeping or failure under vibration and thermal cycling. Allstar Performance's manufacturing ensures tight tolerances and hardened aluminum construction, critical for withstanding pressure spikes during cold-start conditions and high-RPM operation. The compact 4.2-inch width allows integration into space-constrained engine compartments without sacrificing cooling circuit efficiency or hose routing clarity.

This adapter is ideal for custom engine builds, LS swaps, and carbureted or fuel-injected platforms where OEM cooling passages are inadequate or unavailable. Installation requires access to a threaded port on the engine block—common on race blocks and many modern performance castings—and basic hose routing knowledge. Pair this flange mount with a quality aluminum or plate-fin oil cooler and stainless braided -10AN line to achieve consistent 180–200°F oil temperatures under sustained load, preserving ring seal integrity and fuel economy while protecting bearing film.
