Q: i bought these plugs and the gap is bigger then i need. i need like 0.30 was i supposed to
say that when i ordered them or how can i get the gap smaller ? for 3.5l ecoboost ?
A: As these plugs support quite a few vehicles, it's going to be up to the end user to adjust the gap for their particular application. Quick search on youtube will show how easy it is to gap plugs. Just remember it is important that you avoid touching the center electrode while gapping, as it is fairly fragile.
