Positioned tightly within the aluminum cylinder heads, the coils are subjected to intense, continuous heat cycles. This prolonged exposure breaks down the internal epoxy potting and the external rubber boots, leading to microscopic cracking. Once the dielectric insulation is compromised, high voltage arcs directly to the engine block instead of bridging the spark plug gap. This voltage leak causes distinct mechanical symptoms: persistent misfires, a rough and stumbling idle, noticeable hesitation under acceleration, and compromised fuel economy, which is especially disruptive to the hybrid drivetrain synchronization found in these specific chassis.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis ignition coil and iridium spark plug kit is engineered to directly resolve OEM thermal failures. The upgraded coils feature heavy-duty internal copper windings surrounded by a high-dielectric thermal epoxy resin, maximizing voltage output while resisting extreme engine bay temperatures. Paired with these coils are premium iridium spark plugs, utilizing an ultra-fine wire center electrode and a laser-welded ground electrode. Iridium's exceptionally high melting point ensures the spark gap remains perfectly consistent over thousands of heat cycles, preventing voltage blowout under heavy engine load. Together, this optimized system guarantees rapid flame kernel growth for complete combustion, restoring lost torque, stabilizing the idle, and eliminating intermittent misfire codes.\u003c\/p\u003e\n  \n  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2014-2018 Infiniti Q50, Q70\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eVQ35HR (3.5L V6) \/ V37, Y51\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e360 hp \/ 403 lb-ft (Combined Hybrid Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2014-2018 Infiniti Q50 (3.5L V6 Hybrid)\u003c\/li\u003e\n    \u003cli\u003e2014-2018 Infiniti Q70 (3.5L V6 Hybrid)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Infiniti Precision Caliber\u003c\/h3\u003e\n  \u003cp\u003eFor high-performance JDM luxury platforms, maintaining precise ignition timing is crucial for reliable power delivery.
