COBB Spark Plugs - Subaru WRX STI (VA) / Impreza WRX/STI (GE/GH/GR/GV) / Impreza WRX/STI (GD/GG) - Set of 4

These are the factory spark plugs fitted to the 2019-on Subaru WRX STI, sold as a set of four. Compared with earlier factory plugs they are one heat range colder with a slightly tighter gap, which makes them a good off-the-shelf upgrade for modified 2.5-litre turbo Subarus, as well as a direct replacement on the later STI.

Note: For 2.5-litre turbo EJ engines: WRX STI (VA), 2008-2014 Impreza WRX and WRX STI, 2004-2007 Impreza WRX STI and 2006-2007 WRX, Liberty GT 2.5 turbo (BL/BP) and Forester XT 2.5 turbo (SG/SH). Installation by a professional is recommended.

Features

  • Factory plug for the 2019-on WRX STI
  • Heat range 7, one step colder than earlier factory plugs
  • 0.6mm (.024") gap
  • Laser-welded iridium-tipped centre electrode
  • Trivalent metal plating
  • Set of 4
