Unique One-Piece Housing:The smooth one-piece sealed housing, constructed of heat-resistant cross-linked polyethylene (XLPE), features our patented filter-to-housing interface. Its innovative design minimizes the total number of parts, making for an easy installation. A large, clear sight window allows for hassle-free filter inspection, without having to disassemble your system. An auxiliary air inlet is available for use to bring in additional air from the engine compartment in cold climates or can be closed with an included plug if desired.
