Ignition Coil Adapter Loom Set for 3.0 twin‑turbo straight‑six applications

Refresh the ignition wiring on your boosted six with this plug‑and‑play coil adapter loom set. Designed to pair with the popular PR Performance coil conversion, this six‑piece harness kit replaces tired, brittle or damaged adapters and keeps your coil‑on‑plug upgrade delivering rock‑solid spark.

We have fitted these in‑house and they are spot on. Clean installation, OE‑style connectors, proper strain relief and heat‑resistant sheathing for long‑term reliability. Customers love the tidy fit and the way it cures intermittent misfires caused by old or poor‑quality adapters.
