Car and motorbike manufacturers, dealers and workshops have been relying on the ignition specialist's expertise for decades. NGK Laser Iridium spark plugs are first-class technology of the highest calibre! The precious metal means that the centre electrode of the spark plug can be kept much narrower, allowing the petrol-air mixture to flow more easily between the centre and ground electrodes and therefore be better ignited. The result: Significantly improved cold start behaviour and more efficient combustion than with conventional spark plugs, the fuel is optimally utilised. The advantages: Improved ignition behaviour, optimised starting behaviour and smoother running – with lower fuel consumption and reduced environmental impact. An investment that pays off! In both motorsport and everyday use, the high-performance metal iridium ensures top performance. Laser Iridium spark plugs provide the ideal ignition for modern engines. The most important car manufacturers rely on this technology, which is also available to the aftermarket. Longer service life: The use of the precious metal extends the service life of the spark plug compared to standard spark plugs. Optimised starting behaviour: The laser-welded, ultra-fine iridium centre electrode ensures perfect ignition performance and promotes the spread of the flame front in the combustion chamber. Economical in consumption: The excellent ignition capacity contributes to more efficient engine performance, reduces fuel consumption and environmental pollution. Note: Please observe the general installation instructions before installation! Review: 2002 Toyota Rav4 2.0 Petrol - Service.

NGK says it does fit my 2006 Camry 4 cylinder. However, there is a SIFR6A11 in the NGK site at a much higher cost. A warning comes up that it does NOT fit my vehicle. **Q: Is this just a single spark plug ? or a set of 4 spark plugs?** A: Come in single one , I bought 8 for my sequoie **Q: Do i need to use anti-seize on these spark plugs?** A: From what I read, you should always use anti-seize. I did and the little bit of money that it cost gives me a better piece of mind. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 2002 Toyota Rav4 2.0 Petrol - Service.
