For those of us blessed (in a bad way) to have the older two piece spark plugs - Brisk USA makes racing spark plugs that are a one piece design. They are the 3VR17YS Silver Racing plugs. These plugs are very expensive but, no more broken plug worries.

I used the Brisk plugs in my 2010 GT, with Roush M90 blower, gapped to .035". My misfires dropped to zero.

Accel makes a 1-peice plug for our cars. I had an issue with one so currently 7 accel plugs and one old Brisk.
