It’s CNC-machined from high-grade aluminum for superior strength and long-term heat resistance—an ideal replacement for the OEM plastic housing that’s known to warp and leak over time. The housing comes finished in black anodizing to guard against corrosion and adds a clean, high-quality look to your engine bay. It features a two-bolt flange design for quick installation and a reliable seal, and includes a new O-ring and stainless steel hardware for a complete install right out of the box.
