Review ARCTIC CAT Oem Oil Breather Update Kit Nos

The **Arctic Cat 0637-493 Oil Breather Kit** is a precision-engineered maintenance solution designed to enhance the performance, longevity, and reliability of Arctic Cat snowmobiles, ATVs, and other small engines by optimizing oil system efficiency. This high-quality kit is specifically crafted to address the critical function of oil aeration control, preventing harmful air from entering the crankcase and reducing oil degradation, sludge buildup, and engine wear. At its core, the kit features a **closed-loop oil breather system**, which replaces the traditional open-crankcase design, significantly lowering the risk of oil contamination and moisture ingress common culprits behind premature engine failure. The system incorporates a **high-performance oil separator** that efficiently filters out airborne particles and moisture, ensuring cleaner oil circulation while maintaining optimal crankcase pressure. This not only extends the life of the engine oil but also reduces emissions by minimizing blow-by gases that would otherwise escape into the atmosphere. The kit is engineered with **durable, corrosion-resistant materials**, including reinforced hoses and a robust breather housing, to withstand the harsh conditions of off-road use, extreme temperatures, and prolonged exposure to moisture. Installation is straightforward, requiring minimal tools, and the kit is designed to seamlessly integrate with Arctic Cat s existing oil system, ensuring a perfect fit without modifications. Whether used in high-performance snowmobiles, utility ATVs, or other small engines, this breather kit is an indispensable upgrade for operators seeking to maximize engine efficiency, reduce maintenance costs, and protect their investment from the detrimental effects of oil aeration. By maintaining a stable and clean oil environment, the **0637-493 Oil Breather Kit** helps preserve peak engine performance, ensuring reliable operation for years to come.

### Pros and Cons of buying a Arctic Cat 0637-493 Oil Breather Kit

1. **Improved Engine Protection** The oil breather kit helps reduce oil aeration, which can lead to foam buildup in the crankcase. This minimizes engine wear and extends the life of critical components like bearings and seals.

2. **Reduced Oil Consumption** By preventing excessive oil aeration, the kit helps maintain proper oil levels, reducing the frequency of oil top-ups and potential oil starvation issues.

3. **Enhanced Performance** Less oil foam means better lubrication, which can improve engine efficiency and power output, especially under heavy loads or in demanding conditions.

4. **Prevents Carbon Buildup** Excessive oil aeration can contribute to carbon deposits in the combustion chamber, which can reduce performance and fuel efficiency. The breather kit helps mitigate this risk.

5. **Compatibility with Arctic Cat Engines** This kit is specifically designed for Arctic Cat engines, ensuring a proper fit and optimal function without modifications.

6. **Easy Installation** The kit is relatively straightforward to install, often requiring minimal tools and time, making it a convenient upgrade for DIY enthusiasts.

7. **Cost-Effective Long-Term Solution** While the upfront cost exists, the kit can save money in the long run by preventing costly engine repairs related to oil aeration and carbon buildup.

1. **Upfront Cost** The kit is not a free upgrade; it requires an initial investment, which may be a consideration for budget-conscious buyers.

2. **Maintenance Requirement** While the kit reduces oil aeration, it does not eliminate the need for regular oil changes and engine maintenance. Users must still follow Arctic Cat s maintenance schedule.

3. **Potential Misinstallation Risk** If not installed correctly, the kit could fail to function as intended, leading to continued oil aeration issues. Proper installation knowledge is essential.

4. **Limited Lifespan** The components in the breather kit (such as filters or seals) may wear out over time and require replacement, adding to long-term costs.

5. **Not a Cure-All** While the kit addresses oil aeration, it does not fix other potential engine issues like leaks, worn seals, or fuel system problems. It is part of a broader maintenance strategy.

6. **Availability and Part Fit** Ensure the kit is compatible with your specific Arctic Cat model (e.g., 0637-493 may be for certain engines like the 600 or 700 series). Double-checking the part number and application is crucial.

The Arctic Cat 0637-493 Oil Breather Kit is a valuable upgrade for owners looking to protect their engine from the detrimental effects of oil aeration. The benefits such as improved lubrication, reduced oil consumption, and extended engine life outweigh the minor drawbacks, particularly for those who prioritize long-term engine health. However, it is not a standalone solution and should be part of a comprehensive maintenance routine.

For most Arctic Cat owners operating their machines in demanding conditions (e.g., heavy-duty snowmobiles, ATVs, or UTVs), the kit is highly recommended. If budget is a concern, weigh the potential long-term savings against the upfront cost, but the investment is likely justified for serious users.

Purchase the Arctic Cat 0637-493 Oil Breather Kit if you own a compatible model and want to enhance engine longevity and performance. Ensure proper installation and pair it with regular maintenance for optimal results. For those on a tight budget, prioritize this upgrade after addressing more critical maintenance needs like oil changes and filter replacements.
