Ignition Coils for Maserati Gran Turismo (2008-2019)

Direct-Replacement Ignition Coils for 2008-2019 Maserati Gran Turismo

Designed to restore optimal spark energy and eliminate misfires: These ignition coils serve as a direct OEM-equivalent replacement for the F136 V8 engine, resolving rough idle and acceleration hesitation caused by degraded factory coil packs.

The Stock Gran Turismo Ignition Weakness

The factory ignition coils on the Maserati Gran Turismo's F136 V8 engine are situated in an environment subjected to extreme thermal cycling. The primary issue with the OEM design is the eventual degradation of the internal epoxy resin and secondary windings due to prolonged exposure to intense engine bay temperatures. Over time, this constant heat soak creates micro-fractures in the coil housing and boot insulation. Once this thermal breakdown occurs, the electrical current begins to arc to the cylinder head rather than bridging the spark plug gap. This parasitic loss of voltage manifests as intermittent P0300-series misfire codes, erratic idling, distinct power loss in the upper RPM band, and unburnt fuel prematurely degrading the catalytic converters.

The Engineering Solution

Replacing the failing factory units with this complete set of 8 ignition coils ensures a fully restored ignition cycle with consistent high-voltage output. These replacement coils are manufactured utilizing upgraded, heat-resistant epoxy and high-dielectric silicone boots that withstand the punishing thermal environment of the M145 chassis. The internal copper windings are precision-wound to match OEM resistance specifications, ensuring the Engine Control Unit (ECU) recognizes the correct primary ignition draw. By maintaining optimal spark duration and intensity, this replacement set ensures complete combustion across all eight cylinders. This direct plug-and-play solution prevents further catalytic converter degradation, stabilizes air/fuel mixtures, and restores the aggressive throttle response inherent to the naturally aspirated Ferrari-derived V8 architecture.
