Upgrade - Dual Wideband for Haltech Elite 750

Dual wide band option for engine management kits

Add this to a EFI conversion kit to upgrade from single to dual wideband O2 sensors (Bosch LSU 4.9) on a Haltech Elite 750-based EFI conversion kit. Upgrades a kit from HT-159976 WB1 Bosch to HT-159986 WB2 Bosch.

This is just an item created for the price difference from a single O2 to dual O2! Purchasing this alone will not get you the dual O2 kit.
