Positioned directly above the exhaust manifolds in the tightly packaged W-body engine bay, the OEM coils endure continuous and extreme heat soak. This harsh thermal cycling breaks down the internal epoxy potting and degrades the primary winding insulation, leading to a steady increase in electrical resistance. As a result, the stock coils fail to generate sufficient spark energy under heavy engine load. Symptoms often manifest as a noticeable hesitation during acceleration, a rough and stumbling idle, worsening fuel economy, and eventual P0300-series random misfire trouble codes.

Additionally, standard or aging spark plugs degrade under high-compression conditions, widening the spark gap.

This allows moisture intrusion, which compromises secondary voltage delivery.
