These are the OEM spark plugs for most 2004-2019 Subaru EJ25 Turbo Models.  If you’re running less than 300WHP these will be the right choice for spark plugs on your car.  If upgrading beyond this point we would recommend purchasing NGK ILFR7H which are 1-step colder and have a much tighter gap.

Thread Size: 14mm
Hex Size: 5/8″ (16mm)
Reach: 26.5mm (1.04″)
Seat Type: Gasket
Gap: .032″ (0.8mm)

NGK’s Laser Iridium Spark Plugs Provide Superior Ignitability and Long Service Life.

Fine Wire Iridium Tipped Center Electrode and Fine Wire Platinum Tipped Ground Electrode Ensures Slow Wear Rate Providing Stable Idle, Superior Anti Fouling, Improved Fuel Efficiency and Lower Emissions.

  • Trivalent Metal Plating Provides Superior Anti-Corrosion and Anti-Seizing Properties
  • Corrugated Ribs Prevent Flashover
  • Pure Alumina Silicate Ceramic Insulator, Provides Superior Strength and Better Heat Transfer
  • Copper Core Aids in Heat Removal
  • Triple Seals Prevent Leakage

Please Note:
1. Iridium plugs are able to use larger gap setting with less voltage. Some customers choose to re-gap these plugs to correct misfiring or tune for optimal spark — do so at your own risk — slide-type plug gapper will damage the fragile iridium tip.
