08 GT. Will be changing out the plugs for a 3rd time at 300,000 miles. I have used the Motorcraft SP514 twice before, and although I do like the performance and longevity of these plugs, I have broken 3 of 8 each time I changed them out. I also will be changing out the coils. I have the black ones now. What is the absolute best replacement for plug and coil for top performance?

Accel SuperCoils aren't bad.

As for those plugs, yeah, they ain't cheap... You can always find
an equivalent, but hearing how sensitive these engines are, I'd stick
with the OEM.
