Better spark plug for Tucson 2006

[wwilloww]

Hi All, any suggestion for spark plug improvment for a 4 cylinder ( 2.0 liter)engine
what is originally in there , copper, platinum ?

i'm thinking NGK Iridium IX, can somebody point the right part number, also i'm
confused should i go with the (Laser Iridium) or (Iridium IX)

also can i degrade performance with an aftermarket plug ? i mean if the spark is too strong, it could mislead the computer ? to continually make adjustment and make it worse ?

Regards

the car already has platinum plugs in it. I think you will be more than fine with that.
