and also the size of the front flare of the neon blue single flare plugs. and a picture

i want to compare the two plugs 

thanks Myriah i appreciate it  so much

The PTFE plugs are going to vary some on the flares, but they average about 14mm. They are 12.3mm in the wearable :)

The Neons have a front flare of 15mm and the wearable is spot on 13mm.
