Forced Induction Spark Plug Comparison?

[cupcakez]

So I spoke with Sebz and he recommended his spark plugs from SpecialtyZ.

I checked around and I found Z1motorsports also offers spark plugs as well.

The difference between the two?

SpecialtyZ= .6mm welded tip

Z1Motor = .7mm welded tip

Is there really a difference between the two or will both suit me just fine?

The mods in my car:

- KW V3 Suspension
- Stillen Supercharger
- Quaife LSD (1.0)
- Stage 3 Import Parts Pro Long Block (Soon to be installed 11 weeks from now)
- Custom Exhaust with Magnaflow muffler, 4" stainless steel tips

My plan is to make it 700whp++ with the supercharger and other supporting mods.

Any thoughts / ideas / comments / questions / clarifications are welcome! Thanks all :^)
