Extended 36-Inch
Relocation Harness: 36-inch extension relocation wire harness allows you to move knock sensors from the valley pan area to the bottom edge of the engine block. Eliminates the frustrating need to remove the entire intake manifold just to replace or relocate sensors. Plug-and-play with OEM Delphi connectors, pre-wired with color-coded wires no cutting or splicing required
Heavy-Duty Aluminum Gen 3 Knock Sensor Brackets: Brackets are CNC-machined from 6061 billet aluminum, offering superior heat tolerance, corrosion resistance, and anti-vibration strength. Far more durable than plastic knock sensor relocation brackets
Professional Installation Recommended: Due to tight clearances in some chassis (especially 4x4 trucks), professional installation or a well-equipped home workshop is advised. No installation guide is provided; however, basic mechanical knowledge and removal of surrounding components will allow fitment. Not compatible with LQ4 6.0L (Double check most Gen III LQ4 works, but confirm your sensor thread type)
