Infiniti G35 Ignition FAQ's

Please read our FAQs page to find out more.

What spark plugs work best for a tuned Infiniti G35?

A one‑step‑colder iridium plug is common under higher load. Gap to your tuner’s spec—tighter gaps can resist blowout on boosted G35 setups.

Are coil upgrades worthwhile on the G35?

Quality coils can improve spark energy and consistency at higher cylinder pressures. Pair with the correct plugs and dwell settings for the G35 ECU.

Why does my G35 misfire only under heavy load?

Often plug gap, aging plugs, marginal coils, or a small boost leak. Verify fuel quality and tune health before pushing the G35 harder.
