I've been running Autolite AR3933 plugs for years with no problems. Just bought new ones and noticed they are now made in Mexico. This is the differance I've noticed while gaping them. The electrode is shaped differant. Will this make a differance or cause me issues? The one on the left is the new one? Thanks Scott

Here they are side by side. But the new one is on the right now.

Looks like they saved a .010 of an inch of metal by going straighter across instead of the more graceful arc :rolleyes:
