Ignition Coils Set of 6 for Rolls Royce Ghost (2011-2012) 6.6L

Direct-Fit Ignition Coil Pack Set of 6 for 2011-2012 Rolls Royce Ghost (RR4)

What it Does: The ignition coil pack set replaces failing coil-on-plug units on the 2011-2012 Rolls Royce Ghost to eliminate misfire codes, restore spark energy, and ensure smooth idle across the cylinder bank.

The Stock Rolls Royce Ghost Dielectric Breakdown

The twin-turbocharged 6.6L N74B66 V12 produces significant thermal loads within the tight engine bay of the RR4 chassis. Over time, constant thermal cycling degrades the factory internal epoxy potting and fine-gauge secondary windings inside the OEM pencil coils. This deterioration results in high-voltage dielectric breakdown, unmetered spark arcing, and intermittent misfires under twin-turbo boost. In addition, aged silicone boots harden and micro-crack, letting secondary voltage ground out against the cylinder head spark plug tube, triggering DME misfire codes P0300 through P0312.

The Engineering Solution

Engineered to direct factory tolerances, these pencil-style coil-on-plug units use high-grade magnetic laminations and heat-resistant epoxy insulation to withstand continuous engine compartment temperatures exceeding 250°F. Premium silicone spark plug boots maintain elasticity under severe heat soak, isolating secondary voltage and sealing out contaminants from the spark plug well. Fitted with factory-matched 3-terminal blade connectors, these coils drop onto the spark plugs and plug into the OEM engine harness without splicing or adaptation.

Frequently Asked Questions & Fitment Warnings

Does this fit the RR4 Ghost?

Yes, this is a direct fit for the 2011-2012 Rolls Royce Ghost equipped with the N74B66 engine. Note: This package includes 6 coils for one bank; a full vehicle replacement requires two sets for all 12 cylinders.

Should I replace spark plugs at the same time?

Yes, installing fresh plugs with correct electrode gaps alongside new coils ensures optimal primary coil saturation and prevents premature coil failure.

The Rolls Royce Precision Standard

Calibrated to stringent European luxury performance standards, these ignition coils restore exact factory dwell response, preventing DME fault codes and maintaining the vibration-free powertrain delivery expected of a twin-turbo V12.
