Plugs?

Im ordering new plugs and just want to stick with NGK's along with NGK wires since thats what most of you recommended. My question is, is there much of a difference in normal V plugs, Platinum V plugs, and Iridium IX Plugs? I think ill just stick with the normal ones since upgraging probly wont make much of a difference at all. Just wondering what your opinion is.

Stick with the normal ones. No need for performance plugs unless you're runnin' a heavily modded setup.

ive got platnums in my 1.5 litre:D but i really dont feel or see any diff, but i only paid like 50 cents more each, so its all good
