Earl's Performance Engine Oil Cooler
Earl's Performance Engine Oil Coolers: Precision Cooling for High-Performance Engines
When engine temperatures climb under hard acceleration, sustained highway pulls, or track conditions, oil viscosity breaks down and wear accelerates rapidly. That's exactly the scenario Earl's Performance engineered its line of engine oil coolers to address — delivering targeted thermal management for street, strip, road course, and off-road applications alike.
The UltraPro Oil Cooler Line
Earl's flagship engine oil cooler offering is the UltraPro series — a premium, high-performance stacked plate design built from lightweight aluminum alloy. These aluminum stacked plate style coolers are made using state-of-the-art brazing techniques for a durable and long-lasting premium cooler that is highly efficient with minimal pressure drop. That last point matters enormously: excessive pressure drop across an oil cooler can starve bearings and critical engine components, so Earl's engineering emphasis on flow efficiency is a meaningful differentiator.
Designed and engineered to be durable, long-lasting, and highly efficient with minimal pressure drop, UltraPro oil coolers are offered in several width and height options, as well as port sizes, cooling rows, and styles. Specifically, the lineup features narrow, wide, and extra-wide widths, with different heights spanning 7 to 60 cooling rows, and a choice of -10 AN female ports or -16 AN male ports — giving builders the flexibility to dial in exactly the right cooling capacity for their application without over-cooling or under-cooling the oil.
Versatile Port and Fitting Compatibility
These coolers feature -10 AN O-ring female ports and are used with special ORB cooler fittings (-6 AN, -8 AN, -10 AN, or -12 AN) and AN hose ends. For builds requiring increased oil flow, Earl's also stocks coolers with -16 AN male flares brazed on the cooler for applications that require larger ports for additional oil flow. This AN-centric design integrates naturally with the broader Earl's Performance plumbing ecosystem, making it straightforward to build a complete, leak-free oiling system.
Fan Pack Options and Mounting Solutions
Fan pack style coolers are also available with a premium cooling fan and shroud , ideal for installations where natural airflow is limited — think engine bays with restricted air routing, or remote-mounted cooler setups. Earl's oil cooler brackets can be added to UltraPro coolers and allow for easier installation , reducing fabrication time and ensuring a secure, rattle-free mount in virtually any chassis.
Aircraft-Grade Vacuum Brazing Technology
Manufactured from aircraft-spec aluminum alloy using the latest vacuum brazing technology, corrugated screen internal turbulator plates increase both thermal efficiency and mechanical strength — resulting in the most efficient, smallest, and lightest practical package. This commitment to aerospace-level construction means Earl's oil coolers hold up not just to heat, but to the vibration and pressure cycles that are routine in performance driving environments.
Who Benefits from Earl's Engine Oil Coolers?
Race cars, tow vehicles, motor homes, passenger cars, and even motorcycles can realize extended engine efficiency and life with an oil cooler. Whether you're building a dedicated track car, upgrading a turbocharged street machine, or protecting a hard-working diesel or tow rig, Earl's UltraPro engine oil coolers offer a proven, race-validated solution backed by decades of plumbing expertise.
