Ignition coils for 2012 Ford F-150 Ecoboost 3.5L
I bought this so I could change the ignition coils on my father's 2012 Ford F-150 lariat 3.5L ecoboost at 141k miles and so far it has fixed the cylinder 2 and 3 misfire error codes he had and we have driven it for 2 days so far and it has been working good. Runs even smoother then before actually which is a huge plus. I will update if the parts become faulty later.

Great Value
Easy to install , they fixed the issue it my check engine light and shuddering under power. I think there are probably better one out there but for the money they do work. O have not had any issues for approx. 3-4K mikes
