FFP 2015-2023 Ford Mustang Ecoboost NGK LTR7IX-11 Pre-Gapped Plugs
If you’ve purchased a pro tune from us or plan on purchasing one, it is absolutely essential that you upgrade your plugs to these 1 step colder, pre-gapped plugs from Function Factory Performance. What do they do exactly? More boost always equals more heat. These plugs have a colder heat range allowing better heat dissipation. These plugs have been gapped to.026 but if needed we can gap them to .028
- FOR TUNED MUSTANG ECOBOOST ONLY
- These plugs are plug and play and require no additional gapping.
- Do not over-torque your plugs, trust us, you’ll have a bad day. 13 ft/lbs are our recommendations.
- 4 plugs are included
- Do not use anti-seize
- There is an option for E85 use

Changed out the factory plugs for these pre gapped gems in my sons car the other day. Wow, what a difference! They really seem to have pepped the old EcoBoost up ???????

These plugs are clutch for a tuned EBM. Haven’t tossed my new one in yet, sitting on my current plugs for about 15K miles… I’ll get to it now when I need to, easy 20 minute job. But Charles and crew from FFP are making their way into the industry and showing exquisite customer support, so I figure why not. He’s the homie. At least he seems like it I never actually met him before lol
Charles Siritho (store manager) –
