I bought new plugs for our 2010 4.6 Screw. Looking to update the coils while there. Has anybody put MSD Street-Fire coils on their truck?
Thanks,

 

Anything other than MotorCraft coils would be a down grade. There are 20yr old trucks running 9s with 20yr old technology OEM coils there's no need to change them.

Also, they either work or they don't. No need to change them all. Only need to change them if they go out.

Z7What,
Thank you for reply, but more voltage wouldn't hurt. Put a Screamin Demon Coil pack and LiveWires on the wife's V6 Mustang several years ago.
And man it sure woke that puppy up.

 

As 27What stated above, anything other than Ford/Motorcraft ignition parts is a step down, but do as you please.

 

The days of high performance promises are long gone since OEM provide all the power required as far as ignition parts go. Go with Motorcraft and you won't be disappointed.
