Included in the kit is the air filter with clamp, injection-molded lower air box/tray with installed EPDM foam hood seal, Blow Molded clean air tubes, heat extractor foam insert, and all required mounting hardware. The kit utilizes all factory emissions and vacuum lines. Factory mounting locations and hardware are utilized to allow for quick and easy installation.
