The Visconti Tuning B58 S58 Crankcase Vent Heater Jumper restores the factory crankcase vent heater connection on vehicles equipped with flex fuel or ReFlex installations.

Some flex fuel or ReFlex harness installations utilize the factory crankcase vent heater connector for power, leaving the original heater without a connection. This jumper harness restores the factory heater circuit, allowing the crankcase vent heater to remain operational.

Designed for BMW B58 and S58 engines, this plug and play jumper connects directly to the factory wiring and heater without cutting, splicing, or modifying any wiring.

Proudly handmade in the USA with automotive-grade TXL XLPE insulated wire and assembled in an ISO 9001 Certified Facility.
