FORD PERFORMANCE COLD SPARK PLUG SET - FOCUS ST/RS/MUSTANG ECOBOOST (SET OF 4)
Having the right spark plug for boosted engines is paramount. When you add cylinder pressure through increasted boost, a colder spark is required to prevent detonation and potential engine damage.
The performance Irridium Spark Plugs are 2 heat ranges (2-steps) colder than the stock, original equipment spark plugs that come in the Focus ST, Focus RS and Mustang Ecoboost.
These are the same spark plugs that are included in the Ford Performance Power Upgrade Pack.
NOTE: Refer to Tuning Instructions and/or Tuner for correct heat ranges for your application.
