Requires use of a smog pump or delete/eliminator pulley in its place.

*Note

Inlet elbow space with the size of the YSI head unit and valve cover clearance will be limited. We recommend our AF-6582 series valve covers for extra clearance. If you need a tighter elbow you can run AF-90CB40. Due to the design with the swap bracket the inlet elbow may have to rest snug into the valve cover.
