Ignition Coil & Iridium Spark Plugs for Maserati Quattroporte (2014-2020) 3.0L V6

Upgraded Ignition Coil & Iridium Spark Plugs for 2014-2020 Maserati Quattroporte 

Direct replacement ignition upgrade: This comprehensive ignition service kit replaces the factory coils and plugs with a high-energy alternative to restore proper combustion, eliminate misfires, and improve throttle response under high boost conditions.

The Stock Quattroporte Ignition Weakness

The Ferrari-derived F160 3.0L Twin-Turbo V6 is highly susceptible to spark blowout and coil degradation over time. As the factory ignition coils age in the high-heat environment of the M156 engine bay, their internal windings break down, leading to increased electrical resistance. This degradation results in weak spark energy, premature fouling of the spark plugs, rough idling, and hesitation under load. Factory spark plugs also experience accelerated gap erosion from consistent high cylinder pressures. This compounds the risk of misfires and allows unburnt fuel to enter the exhaust stream, which can ultimately damage the sensitive and expensive factory catalytic converters.

The Engineering Solution

This kit addresses these thermal and electrical vulnerabilities by pairing six upgraded 12-volt ignition coils with high-performance Iridium spark plugs. The redesigned coils utilize a superior internal copper wire winding configuration, providing a 15% increase in total energy output over standard OEM counterparts. This robust secondary voltage ensures complete combustion events, even under peak twin-turbo boost pressures. The included Iridium spark plugs feature an ultra-fine center electrode, maximizing conductivity and preventing gap expansion over extended maintenance intervals. Combined with precise 4-pin, blade-style male terminals and female connectors for a direct plug-and-play fitment, this OE+ durability package ensures stable voltage delivery, eliminating high-RPM hesitation and restoring factory horsepower while preventing heat soak-induced failures.
