spark plugs?

i have a 2011 mazda3 s 2.5L. Should i go with the NGK laser iridiums or laser platinums?

ALWAYS iridiums!! How many miles do you have on it? Iridium plugs are good for damn near the life of the car. I change mine every 100k just because I'm old school but the ones I take out always look fine and the car never runs any different with new plugs.

Just use the OE plugs. It's what the engine is designed for.
