salam sir, accordin to my experience, its better to use normal plugs and regularly change them.
iridium just lasts longer sir, in fact they tend to foul more then normal plugs when tuning is done for high end engines. it doesnt produce more spark, or sumthing similar. they just last longer jer, thanx to the iridium electrode. fyi, iridium isnt one of the best conductor around, so the usage isnt to perform but rather for the plugs to last longer imo. if ur plugs are easy to access, then just use normal plugs jer. it may seem like iridium makes sense in the long run, but i prefer to change them regularly..
