OctoMotive Coil Grounding Kit for EA888 Gen 3 & Gen 4 Engines

Coil Grounding Kit for EA888 Gen 3 & Gen 4 Engines

Improve Ignition Performance & Reliability | Octomotive

Solve Common Ignition Coil Misfires with a Reliable Grounding Upgrade

If you’re driving a Volkswagen or Audi with the EA888 Gen 3 or Gen 4 engine, chances are your ignition coils rely on weak grounding through the factory aluminum cam cover. Over time, those soft threads wear out, leading to misfires, spark blowout, and inconsistent performance—especially under boost.

The Octomotive Coil Grounding Kit (CGK) is designed to fix that issue permanently. By providing each coil with a dedicated chassis ground, this kit ensures consistent spark energy and protects your cam cover from damage.

Key Benefits of the Octomotive Coil Grounding Kit

• Eliminate Engine Misfires and Spark Blowout
  Stable ignition coil grounding is critical on tuned engines, especially those running higher boost or ethanol. Our CGK helps prevent spark-related issues caused by high resistance or poor OEM grounding.

• Protect and Preserve Valve Cover Threads
  Avoid common damage to soft aluminum threads. Our kit removes the need to torque into worn or compromised coil bolt holes—reducing long-term maintenance headaches.

• OEM-Compatible, Plug-and-Play Installation
  Built with motorsport-grade materials and OEM-spec terminals, this kit integrates directly with your factory coil harness. No splicing, no guesswork—just clean, effective power delivery.
