Cast from high-grade A356.0-T6 aluminum alloy and holding a full quart over stock, this pan is a perfect upgrade to the factory stamped steel or flimsy plastic versions. We've addressed the major issues associated with the original factory oil pan. Deep external cooling fins radiate heat and help the engine operate at much cooler temperatures than the stock pan. Thanks to its thick, cast aluminum construction, external fins, and the addition of side gussets, this easy-to-install upgrade is stronger and runs cooler than the stock units. The PPE Oil Pan Kit includes a hardened billet stainless steel drain plug which contains a powerful Neodymium magnet that attracts and holds ferrous metal particles, keeping them from damaging your engine's vital internal components.
