NGK RX PREMIUM are the extended version of the NGK IRIDIUM MAX.
These series combine a Ruthenium center electrode of 0.6mm diameter with a ground electrode whose design has been completely revised.
The ground electrode has the particularity to integrate a platinum extension that aims to greatly improve the electrical conductivity and the combustion quality while ensuring an extremely reduced electrode wear.
These spark plugs also feature a brass terminal nut with very low impedance (Ohm), in the same way as Iridium Racing series (IRI-Series NGK and most IRIDIUM MAX).
RX PREMIUM spark plugs insulator has been also completely revised to provide greater heat dissipation and leave more space for the propagation of combustion.
Benefits of NGK RX PREMIUM Series :
- Performances & Lifetime unmatched to date.
- Best compressions (small diameter electrodes / innovative insulation design).
- Increased horse power. - Firmer accelerations with more linearity.
- Maximized tension / Loss Reduction (brass module / Ruthenium electrode / ultra-fine Platinum ground extension).
- Service life of 120 000 km to 140 000 km (20 to 40% more than the Platinum series / Iridium long life).
- Optimized ignition / less misfires.
- Less emissions / Less unburned fuel.
- Better fuel economy with a much more stable ignition (Double alloy use with Ruthenium & Platinum).
- Insulation completely revised, tougher, less imposing.
- Better heat dissipation at an equal thermal index.
- Identical anti-corrosion alloy to NGK IRIDIUM MAX.
- Extended ground electrode & reinforced platinum implant.
- More stable idle.
- Reduced vibration.
- Easy starts in all weather and all conditions of use.
- Stability and durability in the long term.
Benefits of NGK RX PREMIUM (VS IRIDIUM) :
- Performance Gain.
- Increased longevity of 20 to 40% compared to NGK IRIDIUM MAX.
- Increased longevity beyond double compared to NGK Iridium IX.
- Ruthenium undisputed benefits over the stability of the ignition and its corrosion resistance related to combustion effects.
- Cleaner combustion / reduced polluting emissions.
- Better compressions (platinum mass Extension).
- Reduced fuel consumption.
- Significant impact on Ethanol & LPG configurations.
Suitable for conventional vehicles, stock/original and tuned.
