1989–1994 Nissan Skyline GT-R Ignition FAQ's

Please read our FAQs page to find out more.

What plugs/gaps suit tuned/boosted RB26s?

Run one step colder than stock with a tighter gap to prevent blowout at higher cylinder pressures. Follow your tuner’s spec and recheck gap after heat cycles.

Are coil upgrades helpful on older R32s?

High‑output coilpacks 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 for quick diagnostics at events.
