1990–1996 Nissan 300ZX Ignition FAQ's

Please read our FAQs page to find out more.

What plugs and gaps suit tuned/boosted VG30s?

Run one step colder than stock with a tighter gap to prevent blowout at higher cylinder pressure. Follow your tuner’s spec for fuel and target boost.

Are coil upgrades helpful on higher‑power Z32s?

High‑output coils and a healthy PTU improve spark energy and reduce misfire risk at high EGT/boost. Pair with quality leads and verify dwell control in the tune.

How often should I service ignition components?

Inspect plugs and coils regularly; heat and age shorten life. Keep a spare gapped set and fresh leads for quick diagnostics at events.
