Protect your engine from premature wear with the Cusco Neodymium Magnetic Drain Bolt. Engineered for select Toyota and Nissan applications, this high-performance plug serves as a critical line of defense for your lubrication system by capturing metallic contaminants that standard oil filters may miss.

At the core of the bolt is a powerful 5,000-gauss neodymium magnet—one of the strongest rare-earth magnets available. As oil circulates through the pan, the magnet traps microscopic iron shavings and metallic debris, preventing these abrasive particles from reaching critical engine components like bearings and cylinder walls. During your next oil change, simply wipe the magnet clean to remove the captured debris.

• Features a high-strength 5,000-gauss neodymium magnet
• CNC-machined for precise fitment and leak-free sealing
• Captures metallic particulates to extend engine life and reduce friction
• Direct replacement for the factory oil pan drain plug
