Upgrade your engine build with Turner's WPC-treated Race Series Bearings, engineered for serious performance enthusiasts. Starting with ACL’s high-performance bearing shells, these Race Series bearings are built to withstand extreme RPMs and stress. Utilizing a "Duraglide" tri-metal construction and a high-strength overlay plate, these bearings offer superior oiling and heat resistance for high-RPM operation.

Our WPC-treated bearings take ACL’s already impressive design and enhance it even further. The WPC treatment process strengthens and smooths the bearing surface by firing high-speed, ultra-fine particles at the bearing shells, reducing friction and improving durability. This advanced surface treatment ensures smoother operation and improved heat dissipation, which are critical for any high-performance engine.

Key Features:

Duraglide Tri-Metal Construction: ACL's Race Series bearings feature a high-strength overlay for enhanced performance. Optimized Oiling: Designed to promote better oil flow during high-RPM conditions. Precise Fitment: Manufactured with OEM-level precision using micron tolerance machining. WPC-Treated for Strength: Surface treatment adds strength and reduces friction for improved engine performance. No Flash Plating: Allows for better heat transfer and bearing retention. Thermal Discharge Process: Smoother, stronger components through WPC’s unique thermal discharge technology. Enhanced Heat and Friction Resistance: Built to combat the biggest enemies of high-performance engines. Don’t settle for standard bearings—choose Turner Motorsport WPC-treated Race Series Bearings for the ultimate engine performance upgrade. Perfect for your next engine rebuild or rod bearing service!

Maintaining the peak performance and reliability of your BMW N52 engine is essential for a smooth and enjoyable driving experience. One of the most effective ways to achieve this is by replacing critical components like the valve cover, crankcase vent hose, angle connector with heating element, and cylinder sleeve. In this article, we'll delve into the numerous benefits of upgrading these vital parts, ensuring your BMW N52 operates at its best. Optimized Engine Performance: Replacing the valve cover, crankcase vent hose, angle connector, and cylinder sleeve enhances your BMW N52's engine performance. The valve cover plays a crucial role in sealing the engine, preventing oil leaks and ensuring optimal valve operation. When you upgrade these components, you reduce the risk of performance-robbing oil leaks and maintain precise valve timing, resulting in improved horsepower and torque. Enhanced Reliability: Reliability is paramount for any BMW owner. These components, when aged or damaged, can lead to severe engine issues. By replacing them, you significantly reduce the likelihood of unexpected breakdowns or costly repairs, ensuring your BMW N52 engine runs smoothly and reliably for years to come. Improved Fuel Efficiency: An efficiently operating engine not only performs better but also consumes less fuel. The replacement of these components leads to better combustion, reduced emissions, and ultimately improved fuel efficiency. This means fewer trips to the gas station and a lighter environmental footprint. Reduced Maintenance Costs: Regular maintenance and repairs can add up over time. By proactively replacing the valve cover, crankcase vent hose, angle connector, and cylinder sleeve, you mitigate the risk of more extensive engine damage that could lead to expensive repairs down the road. In the long term, this can translate into significant cost savings. Extended Engine Lifespan: The longevity of your BMW N52 engine is directly tied to the quality and condition of its components. When you invest in high-quality replacements, you're effectively extending the lifespan of your engine. This not only preserves the value of your BMW but also allows you to enjoy its performance for years to come. Precise Temperature Control: The angle connector with heating element is vital for maintaining optimal engine temperature, especially in cold weather. A malfunctioning or worn-out connector can disrupt temperature control, affecting engine performance. Replacing this component ensures consistent and precise temperature management. Customized Upgrades: When replacing these components, you have the opportunity to choose high-performance or specialized alternatives, allowing you to customize your BMW N52 to your preferences. Whether you prioritize power, efficiency, or specific driving conditions, there are options available to tailor your engine's performance accordingly. Included in the BMW N52 Valve Cover & PCV Valve Refresh Kit: 6 Cylinder Sleeves 1 Alternator Mounting Screw Set 1 Angle Connector with Heating Element 1 Valve Cover - Gasket Included 1 Crankcase Vent Hose
