Great plugs for your tuned ecoboost, Whoosh shipped them fast, 2nd time if ordered them for routine maintenance. Add Whoosh Coil Packs when you buy these!
Ordered them as a replacement for my oem plugs that haven't been replaced in 80k miles. I heard great things about these plugs so I picked them up.
