Vpowers are always a good safe bet.

but would i get more performance well?
would any of the other types be any better?

You can't 'get performance' from a spark plug without totally upgrading your entire ignition system too. Plugs aren't a power adder. They're a power-restorer for worn plugs.

Reasons to change plugs:

Yours are old. Restores lost power.
You need a colder heat range. Prevents early fouling, restores lost power.
You bought bosch and are kicking yourself. Restores lost power.

In order to gain more power, you need to increase your spark voltage. MSD 8224 coils will gain you a SLIGHT amount except on the 97+ SSEi and GTP. You could also switch to those coils.

well sorry i guess i worded that wrong i realize what you are saying but that gets into a little bit of money i dont have i guess more along the lines of what i was trying to say is what plugs would be more "efficient"
should i just go with the v-power
or the irridium
or even the platinums, would there be any benefits to running one or the other?

Platinums are fine for you, but not for supercharged. Irridiums or copper plugs (like the V-power) would be great. Depends on what you want to pay.

I feel the V-powers provide a more efficient burn, especially with my hotter coils. They provide the same function as the splitfire, but do it in a way that the plug doesn't wear out like the splitfire.
