Best G37 Oil Cooler: Top Picks & Buying Guide

Hey G37 enthusiasts! Are you looking to keep your engine running cool and smooth? Then you're in the right place. Choosing the right oil cooler is crucial for maintaining optimal performance and preventing engine damage, especially if you're pushing your G37 on the track or live in a hot climate. In this comprehensive guide, we'll dive deep into the world of G37 oil coolers, exploring the benefits, key features, and the best options available on the market. We'll help you make an informed decision so you can keep your G37 purring like a kitten, even under pressure.

Why You Need an Oil Cooler for Your G37

Let's get straight to the point: why should you even bother with an oil cooler? Your G37's engine works hard, and all that friction generates heat. Engine oil is designed to lubricate, cool, and clean the engine, but it has its limits. When the oil gets too hot, it loses its viscosity, meaning it doesn't lubricate as well. This can lead to increased wear and tear on your engine components and, in severe cases, engine failure. An oil cooler acts like a radiator for your oil, dissipating heat and keeping the oil temperature within a safe range. This is especially important for those of you who frequently track your car, drive aggressively, or live in warmer climates where engine temperatures tend to soar. By installing an oil cooler, you're not just adding a fancy aftermarket part; you're investing in the long-term health and performance of your G37's engine. Think of it as preventative medicine for your ride. An oil cooler will keep your engine oil at optimal temperatures, preventing the oil from thinning out and losing its lubricating properties. This translates to improved engine protection, reduced wear and tear, and increased engine lifespan. For those who enjoy pushing their G37 to its limits, an oil cooler is an absolute necessity. High-performance driving generates a significant amount of heat, and an oil cooler will ensure that your engine oil remains within a safe operating range, preventing overheating and potential damage. In hot climates, the ambient temperature can put a strain on your engine's cooling system. An oil cooler will help to alleviate this stress by providing additional cooling capacity for your engine oil, keeping your G37 running smoothly even in scorching conditions. So, whether you're a track enthusiast, a spirited driver, or simply want to protect your investment, an oil cooler is a smart upgrade for your G37.

Key Considerations When Choosing an Oil Cooler

Okay, so you're convinced you need an oil cooler. Awesome! But with so many options out there, how do you choose the right one for your G37? Don't worry, we've got you covered. Here are the key factors you should consider:

• Cooling Capacity: This is the most crucial factor. You need to choose an oil cooler that can effectively lower your oil temperature. Cooling capacity is usually measured by the number of rows in the cooler core and the overall size of the cooler. A larger cooler with more rows will generally provide better cooling. Consider your driving style and climate when determining the cooling capacity you need. If you frequently track your car or live in a hot climate, you'll want a cooler with a higher cooling capacity. It's also important to consider the oil cooler's efficiency, which refers to how effectively it can dissipate heat. Look for coolers with high-quality cores and efficient fin designs.
• Size and Placement: Oil coolers come in various sizes, and you need to make sure the one you choose will fit in your G37's engine bay. You also need to consider the placement of the cooler. Common locations include behind the front bumper or in front of the radiator. Placement can affect the cooler's efficiency, as coolers mounted in areas with good airflow will generally perform better. Ensure that the oil cooler you choose fits properly in your G37's engine bay and doesn't interfere with other components. Proper placement is crucial for optimal cooling performance. Consider the airflow around the cooler and choose a location that will maximize heat dissipation. You might need to make some minor modifications to your car to accommodate the oil cooler, such as trimming the bumper or relocating other components. Make sure you're comfortable with this before making a purchase.
• Core Type: There are two main types of oil cooler cores: stacked plate and tube-and-fin. Stacked plate coolers are generally more efficient at cooling, but they can also be more restrictive to oil flow. Tube-and-fin coolers offer better flow but may not cool as effectively. Consider your specific needs and driving style when choosing a core type. Stacked plate coolers offer superior cooling performance due to their larger surface area and efficient heat transfer. However, they can also create more pressure drop in the oil system, which might be a concern for some applications. Tube-and-fin coolers are less restrictive to oil flow, making them a good choice for street cars or applications where pressure drop is a concern. However, they might not offer the same level of cooling performance as stacked plate coolers.
• Thermostat: Some oil coolers come with a thermostat, which regulates the flow of oil to the cooler. This can be beneficial in colder climates, as it allows the oil to warm up to operating temperature more quickly. However, thermostats can also restrict oil flow, so consider whether you really need one. A thermostat helps to regulate oil temperature by only allowing oil to flow to the cooler when it reaches a certain temperature. This prevents the oil from overcooling in colder weather, which can be detrimental to engine performance. However, a thermostat can also restrict oil flow, which might be a concern for high-performance applications where maximum cooling is required. Consider your climate and driving conditions when deciding whether to use an oil cooler with a thermostat.
• Kit Completeness: Oil cooler kits typically include the cooler core, lines, fittings, and a sandwich plate (which mounts between the oil filter and the engine). Make sure the kit you choose includes everything you need for installation. A complete kit will save you time and hassle, as you won't have to source individual components. Check the kit contents carefully to ensure that it includes all the necessary hardware, such as mounting brackets, hoses, and fittings. Also, make sure the kit is designed specifically for your G37, as this will ensure a proper fit and optimal performance.
• Budget: Oil coolers can range in price from a few hundred dollars to over a thousand. Set a budget before you start shopping, and stick to it. Don't be tempted to overspend on features you don't need. Consider your budget and the features you require when choosing an oil cooler. There are many excellent options available at various price points. Don't always assume that the most expensive oil cooler is the best. Research different brands and models to find one that offers the best value for your money. Read reviews and compare specifications to make an informed decision.

By carefully considering these factors, you can narrow down your options and choose the perfect oil cooler for your G37.
