Preguntas frecuentes sobre Infiniti G37 Ignition

Consulta nuestra página de preguntas frecuentes para obtener más información.

What spark plugs are recommended for a tuned Infiniti G37?

A one‑step‑colder iridium plug is common at higher cylinder pressures. Gap to your tuner’s spec—tighter gaps can resist blowout on boosted G37s.

Are upgraded coils useful on the G37 VQ37VHR?

Quality coils improve spark energy and consistency as load increases. Pair with the correct plugs and dwell strategy for the G37 ECU.

Why does my G37 misfire only under heavy load?

Often plug gap, aging plugs, marginal coils, or a small intake/boost leak. Verify fuel quality and tune health before pushing the G37 harder.
