[UNBROKEN]

I’ve tried a few different colder plugs. These by far idle the smoothest.

[UNBROKEN]

Nope. The 6510’s had a noticeable hiccup at idle. 2 different sets.

How the hell do yall get to the back two plugs? They're under a nest of wires and some (what appears to be) AC tubes.

 

[UNBROKEN]

Take the 2 bolts out of the bracket for the hard lines and it’ll move out of the way.

So these motors you do need to change the plugs with tuning (optimal performance)?

The fusion sport came with the colder plugs from ford so surprised to see this. About to tune and was curious if this was the case with the ST so glad I found this.

Bought a set of 6 NGK LTR7BHX (95605) Spark Plug from ZFG. These are the ones Adam recommended to me so that's what I'm going with.
