This kit has traditionally combined 4x Audi R8 "red top" COPs (coil on plug) with 4x semi-assembled wiring connectors. New for spring '23 season, they're available in black, too. (Some go farther speaking quietly while carrying a big stick.)
The builder is responsible for integrating flying leads into a finished wiring harness, trimming rubber boots (or modifying valve cover), etc. A more completely integrated kit variant will be released later this year.
Coils shown installed along with the VW 16V "EVO" Trigger Adapter.
Why convert to COPs, in the first place? A coil for each cylinder reduces coil charging time and allows for stronger spark output. This is especially important at high revs when a single coil may not have time to adequately charge. It's critical for avoiding misfires under big boost, too. Fully modern, igniters are built into these coils, enabling direct switching by the ECU. Lastly, spark plug wires are eliminated from the engine bay. This means less electro-magnetic interference in the engine bay. -interference that can vex an ECU and frustrate tuning.
Cleaner looks don't hurt, either! So, we also offer black COP Looms and red COP Looms to discretely contain everything:
