I noticed that some hotter coils from summit are not really that bad priced for a set of 8 between 180-250 bucks.

Mines an 08 5.4 has anyone done this? i know on all my older trucks a hotter coil made hella difference and should on the new ones too right?

 

I had one of the originals go out on my 05 5.4 and ended up replacing them all with these Accel coils and I have had zero issues with them. They are supposed to be a stock replacement.
