Product Description

Perfect for your Veloster Turbo with upgrades/tune!!!  HKS M-Series Super Fire Racing spark plugs are high performance  Iridium plugs designed to handle advanced levels of tuning and provide  Improved ignition performance, durability and anti-carbon build-up

M-Series Super Fire Spark Plugs Feature:

  1. 0.6mm Iridium Alloy Center Electrode Iridium Alloy Center Electrode reduces voltage requirement as well as improving ignition performance and durability.
  2. 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.
  3. 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.
  4. 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.
  5. 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.

*M Series is recommended for reliable ignition, durability and anti-carbon buildup under high load.

The Iridium alloy is used because of its durability and  reliability.  On an average plug, a narrow core typically shortens life  span of plug but with the intense durability of iridium there is no  sacrifice in any longevity.  With a high melting point of 2454 degrees  C, opposed to the 1769 degrees C of white gold, the electrode can  tolerate the high levels of compression and minor knocking without any  deterioration. A nickel coating on the housing also prevents the spark  plug from premature deterioration.  The Iridium plugs are available for  multiple applications and offered in €œcolder€ heat ranges of 7 and up  and specifically for rotary, heat ranges of 9 and up are offered.
