NGK Spark Plug 4177 - TR6
Great for Mild Forced Induction / Nitrous Applications or Engines with 11:1 + Compression
The NGK TR6 Spark Plugs are a great plug for Mild to Moderate Forced Induction / Nitrous Applications and Modular Engines with more than 11:1 Compression that require a colder than stock plug. We recommend these plugs for anything up to 15lbs of boost or 150 Hp Nitrous. Anything more we prefer the NGK BR7EF Plug.
