Product Highlights

    Why Choose EVIL ENERGY Oil Coolers?

    • Superior Heat Dissipation: Every engine oil cooler we produce is tested to significantly lower oil temperatures, reducing internal friction and protecting vital engine seals.
    • Specialized Performance: For those running high-performance swaps, such as an LS oil cooler kit configuration, our systems provide the flow rate necessary to keep large-displacement engines running cool.
    • Durable Aluminum Construction: Crafted from high-grade aluminum, the EVIL ENERGY oil cooler is built to withstand extreme pressure and vibration in professional racing environments.
    • Universal Compatibility: With AN6 and AN10 compatibility, our oil cooler kits allow for flexible, leak-free installation across a vast range of vehicle platforms.
    • All-in-One Convenience: We provide complete oil cooler kits that include everything needed for a hassle-free upgrade, ensuring your engine oil cooler kit is ready for the street or the strip.

    Understanding the Cooling Process

    An engine oil cooler works by circulating hot lubricant through a series of fins and plates. As air passes through these fins, heat is transferred from the oil to the atmosphere.

    Pro Tip: After installing an engine oil cooler kit, always check your levels. It is also important to know how long to let the engine cool before adding oil (typically 15-30 minutes) to ensure you get an accurate reading on the dipstick and avoid thermal shock to the system.

    Whether you are building a professional drift car or a daily-driven turbo project, EVIL ENERGY oil coolers provide the cooling stability and performance gains required to push your vehicle to its absolute limit—safely.

    From professional track builds to daily-driven turbocharged cars, EVIL ENERGY oil coolers provide the cooling stability and performance gains you need to go farther, faster—safely.

    Mastering Engine Temperature Control

    Maintaining optimal thermal efficiency is the key to vehicle longevity and performance. Whether you are navigating heavy traffic in a daily driver or pushing a high-horsepower LS engine swap to its limits, managing oil temperature is a critical task. This guide explores the essential role of an oil cooler and explains how integrating a high-quality engine oil cooler kit—such as the performance-grade EVIL ENERGY oil cooler—can safeguard your engine against thermal breakdown and premature wear.

    An oil cooler is a specialized heat exchanger designed to remove excess heat from a vehicle's engine oil. Much like a radiator cools coolant, the engine oil cooler ensures that the lubricant stays within its optimal temperature window, preventing thermal breakdown.

    For high-performance enthusiasts, a standard setup often isn't enough. This is why an engine oil cooler kit is a popular upgrade. These kits, such as the high-flow EVIL ENERGY oil cooler, consist of an external heat exchanger, specialized hoses, and adapters.
    Common Use Cases:
    1. LS Engine Swaps: Builders frequently utilize an LS oil cooler kit to manage the high thermal output of Gen III/IV small blocks in tight engine bays.
    2. Performance Tuning: Track day participants and drifters rely on oil cooler kits to keep oil from thinning out under redline conditions.
    3. Heavy Duty Towing: Truck owners use an engine oil cooler to protect the engine when hauling heavy loads over steep grades.

    The primary function of an engine oil cooler is to maintain the chemical integrity of your motor oil. When oil gets too hot, its viscosity drops (it becomes too thin), which can lead to metal-on-metal contact and catastrophic engine failure.
    Key Functions & Benefits:
    1. Thermal Regulation: An oil cooler stabilizes temperatures during aggressive driving.
    2. Extends Component Life: By using an engine oil cooler kit, you reduce the stress on seals, gaskets, and bearings.
    3. Maintains Lubrication Stability: An EVIL ENERGY oil cooler uses high-efficiency stacked-plate or tube-and-fin designs to ensure oil maintains the proper "film strength" needed to protect internal parts.
    4. Optimized for LS Platforms: An LS oil cooler kit specifically targets the unique oiling needs of Chevy LS1, LS3, and LS6 engines, which are prone to high oil temps during spirited driving.
    Targeted User Groups:
    1. Off-Roaders: Keeping oil cool while crawling at low speeds with minimal airflow.
    2. Daily Drivers in Hot Climates: Providing an extra layer of protection against summer heatwaves.

    If you are performing maintenance or installing a new engine oil cooler kit, safety is paramount. You should generally let the engine cool for 15 to 30 minutes before adding oil.
    Why Wait?
    1. Accuracy: Waiting allows the oil to drain back into the pan, giving you an accurate reading on the dipstick—especially important when calculating the extra capacity required for new oil cooler kits.
    2. Safety: Engine components and the oil cooler itself can reach temperatures over 200°F. Touching a hot engine oil cooler or pressurized lines can cause severe burns.
    3. Thermal Shock: Adding very cold oil to a blistering hot engine can, in extreme cases, cause minor stresses to the metal.
    Installation Context:
    When installing an LS oil cooler kit or an EVIL ENERGY oil cooler, always perform the work on a stone-cold engine. This ensures that the oiling system is not pressurized when you remove the oil filter or install the sandwich plate adapter included in most oil cooler kits.

    FAQs about Oil Coolers

    What is the function of the oil cooler?

    An oil cooler helps regulate engine or transmission temperatures by dissipating heat from the oil as it circulates. Whether it's an engine oil cooler or motor oil cooler, its purpose is to prevent oil breakdown, reduce wear, and improve performance—especially under high RPM or load.

    In aviation, an oil cooler has the same role—cooling engine oil to avoid thermal stress and ensure proper viscosity. While aircraft engines require more robust cooling, the principle mirrors that of automotive systems like EVIL ENERGY oil coolers.

    Oil coolers are found in cars, motorcycles, trucks, aircraft, and industrial engines. In auto applications, EVIL ENERGY oil coolers are commonly used in turbocharged, track, or towing builds to reduce heat and prevent oil in cooling system contamination.

    An oil cooler functions by channeling hot oil through a radiator-style aluminum core. Airflow (natural or fan-assisted) removes heat. A full oil cooler kit includes AN lines and fittings to ensure leak-free, efficient flow.

    Yes. A quality oil cooler kit significantly lowers oil temperature, improves lubrication, and maintains consistent viscosity. It helps prevent overheating and boosts reliability for performance, towing, or racing builds.
