That gap is too tight especially with upgraded coils. You should start from stock gap ~0.028"-0.032" (this is in inches) and gap down as needed.
Because an overly tight gap makes it harder to get complete combustion and can cause harsh rough idles. You only gap down to prevent spark blow out, which is less likely to occur with more powerful upgraded coils. |
