While the Denso spark plugs that come stock in Infiniti vehicles are good quality, other brands make equally good products. Some people prefer NGK over Denso, while others like Bosch or Autolite better. Ultimately, it comes down to personal preference and what you think works best for your car.
Notice
Iridium-tipped spark plugs last much longer than conventional-type spark plugs, so they do not need to be replaced as often. When replacing spark plugs, it is important not to reuse them and always use the recommended or equivalent replacements.
