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
http://specialtyz.com/shop/370z-g37/...ark-plugs.html


Z1Motor = .7mm welded tip
https://www.z1motorsports.com/igniti...ug-p-6053.html

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 :^)

My tuner always recommends OEM GTR plugs.

GTR Plugs for me too. I ordered them from Z1.

edit: the Z1 link you provided is indeed for the GTR plugs.

Thanks guys!
Sounds like I will purchase the ones from Z1 from the link I put up in the OP.

Although, it would still be interesting to find out the difference between SpecialtyZ spark plugs [vs] Z1 motorsports as the size difference is about .10mm apart, haha.
Looks like one is made in Japan the other is not, as I do not see the word "Japan" on the other one xD

welcome, make sure you buy 6 lol

Thanks to their core credit program, I was able to send in my OEM upper intake plenum and then once I receive $150 credit from them for their store, I will be able to purchase (x6) of them! Yay!

I bought a set of GTR iridium spark plugs from rockauto for like $90 a year and a half ago. Just a thought

Much cheaper here too. $99.95 for a set of 6.

Checked the part number.

Matches with the ones everyone gets:

The best price I found on them was RockAuto.com

So a tuner says user the GTR plugs, but can I get some reasons behind it? I know they are like a step colder but what does that mean for combustion? Why does it matter with FI? Im just clueless haha
