• CNC Machined Seal: Precision-machined flange ensures leak-free fit with reusable gasket included.
• Heat-Dissipating Fins: Internal and external fins increase surface area to pull heat away from fluid faster than stock pans.
• Neodymium Magnets: Two large rare-earth magnets trap ferrous metal particles to protect internals from wear.
• Includes pan gasket, magnets, drain plug, and mounting hardware for complete installation.
• Cast A356-T6 aluminum for strength and corrosion resistance in demanding diesel applications.
