The Massive Trapped Oil Drain Plug (Magnetic) is engineered for performance enthusiasts and serious engine builders who demand maximum protection and reliability. Featuring a powerful neodymium magnet, this drain plug captures harmful metallic particles in your engine oil preventing them from circulating and causing premature wear. Its hybrid O-ring seal, made from genuine Fel-Pro BUNA N rubber, ensures a leak-free fit thats fully reusable, unlike cheap crush washers that fail over time. The large 1 hex head provides superior tool engagement for easy removal without rounding, while the 7075 aluminum alloy construction offers exceptional strength, corrosion resistance, and compatibility with aluminum oil pans to prevent galvanic corrosion. Zinc-plated magnet housing withstands extreme heat up to 590F without losing magnetism, making it ideal for high-performance applications and frequent oil changes. Precision-built to fit M12 1.75 metric threaded oil pans found on I4 Duratec, MZR, and Ecoboost engines, this plug is built to last and look great doing it.
