Nissan Stagea C34 260RS Spark Plug RB26DETT (NGK Range 6)

The Nissan Stagea C34 260RS equipped with the RB26DETT engine requires precision tuning to maintain both reliability and performance, especially under boost. One of the most critical choices for this platform is selecting the correct spark plug heat range. For Stagea models running higher cylinder pressures or increased boost compared to stock, the NGK range 6 spark plug provides the ideal balance.

A range 6 plug is considered colder than a range 5, meaning it dissipates heat from the combustion chamber more efficiently. This reduction in retained heat helps prevent pre-ignition and detonation, two common risks in turbocharged engines operating at higher load or elevated temperatures. For owners who have upgraded their Stagea with mild performance modifications, or who regularly drive in demanding conditions, the range 6 plug offers the right protection without sacrificing drivability.

While a range 5 plug works well for stock setups, it can retain too much heat under higher boost, potentially leading to engine damage. Conversely, moving to a colder plug like the range 6 ensures controlled combustion, cleaner ignition, and safer operation during spirited driving or tuning upgrades. Only when power levels and boost reach extreme levels should a colder range 7 plug be considered.
