Description Post A Question
These are 1 heat colder iridium spark plugs by HKS for Nissan/Infiniti. Recommended for vehicles with at least 100hp difference from stock.

  • Nissan 350Z [Z33] (2007, 2008)
  • Infiniti G35 [V35] (2007, 2008)
  • Infiniti G37 [V36] (2009, 2010, 2011, 2012, 2013)
  • Nissan 370Z [Z34] (2009, 2010, 2011, 2012, 2013, 2014, 2015)
  • Nissan GT-R [R35] (2009, 2010, 2011, 2012, 2013, 2014, 2015)
  • 0.6mm Iridium Alloy Center Electrode: Iridium Alloy Center Electrode reduces voltage requirement as well as improving ignition performance and durability.
  • Outer Electrode with Platinum Chip: The Outer Electrode incorporates a square platinum chip which improves durability, and when combined with the iridium center electrode boosts ignition performance.
  • Short Type Outer Electrode (Anti-Vibration): The outer electrode has been shortened and engineered with the ideal shape to decrease weight for resistance against vibration. This anti-vibration design improves longevity of the outer electrode.
  • Thermal Edge: After long idling or various combustion conditions carbon buildup can occur causing misfires. The Thermal Edge of the ceramic insulator will discharge to help decrease carbon deposits.
  • Spark Support Gap: Discharges will occur in the Spark Support Gap (space between the tip of insulator and the base of the outer electrode) to help prevent carbon buildup.
