is anyone running denso iridium racing spark plugs?
is there any real difference in performance? comparing to iridium power spark plugs?
now i use iridium power IK27. i am thinking about IK02 27 racing.....

i used to use IK22 on mine and they were fine for a moderate tuned 4efte, heat range 7

at the racing plug the central iridium electrode is not projected like as it is at the normal iridium plug. also the ground electrode is made out of platinum which is increasing durability.

the racing plug has smaller gap, and i don't know if that could be a problem....

iridium power is just fine if your running a moderate tuned engine

it is more than moderate. forged with garrett 28rs turbo and 440 supra injectors.
i am already running ik27 iridium power. i was wondering if there will be any gain if i change to ik02 27 iridium racing......
i just need an opinion if they are worth buying, because they are much more expensive than iridium power spark plugs....

noone is running denso iridium racing spark plugs?
