- V-Power Tip
- Less fouling
- Longer lasting
- Smaller hex for easier access when head temperature sensor is used
- Cheaper than iridium spark plugs
WHY THE V-TIP MATTERS
- Stronger, more consistent spark exposure - The V-groove effectively “opens up” the spark area, making it easier for the flame kernel to form and grow. In high-revving engines (like karting or racing engines), that initial flame development is critical.
- Improved ignitability (especially lean mixtures) - A lean fuel mixture is harder to ignite. The V-Tip helps concentrate the spark energy right where the air-fuel mix is most combustible, improving reliability when conditions are marginal.
- Reduced quenching effect - Flat electrode surfaces can “suck away” heat from the spark (quenching it). The V shape reduces this contact area, so the spark survives better and ignites the mixture more consistently.
- Better throttle response and high-RPM stability - Because combustion starts more reliably and quickly, the engine tends to feel crisper—especially under load and at high RPM where ignition stability is everything.
NGK is the leading manufacturer of spark plugs supplying millions of spark plugs every year. Their range fits the majority of Australian vehicles and they are tested for even the harshest conditions.
