(CA) HEAT RISER ADAPTER Windage Trays Nitrous pressure directly affects flowThis heat riser adapter (ADAPTER) is designed for California emissions vehicles requiring functional heat riser systems for cold start drivability. The heat riser directs exhaust heat to the intake manifold during warm up improving fuel atomization and reducing cold engine stumbles. This adapter replaces damaged or missing components on applications where emissions compliance is required for inspection purposes and proper cold weather operation.
