Pre gapped NGK 95606 Ruthenium Spark Plugs (1 Step Colder) Ford Ecoboost
NGK Part #95606
Set of 4 precision gapped plugs. Why buy pre-gapped plugs? Precious metal plugs are very fragile, and not using a proper tool to gap them can risk damaging the precious metal coating on the center electrode. No item should put force against the center electric ideally. Common mistakes are using a coin shaped tool to gap the plugs. This will scratch the iridium coating on the electrode and may cause misfires/poor combustion which can result in knock.
1 Step colder spark plug for the following vehicles:
- Fiesta ST
- Focus ST
- Focus RS
- Mustang Ecoboost
- F150/Raptor Ecoboost
Pre gapped to 0.026 for compatibility with our tuning and any other performance tune.
Due to increased crankcase blow by on performance tunes we recommend changing these ruthenium plugs out every 30k miles at least to avoid misfires.
Price is for a set of 4 plugs pre gapped (F150 V6 Ecoboost owners will need to buy at least 2 sets. It is better to buy 3 sets as you will have a complete second set of plugs to change at 30k miles.
