B5 S4 Coilpack Wiring Harness kit for B5 S4 / A6 / Allroad 2.7T

Made in house, upgrade your OEM 3-pin coilpacks and ICMs with 2.0t/R8 coilpacks and completely eliminate the weathered original wiring at the same time. 

This harness connects pins direct into your ECU, designed to layover the existing harness, meaning if you remove the engine, the harness is not trapped in the firewall/ECU box.
