How long do the NGK iridium spark plugs last? I am getting close to 30k on mine and I was gonna replace them just for routine maintanence, but I had heard that iridium plugs are good for 80k. I wasn't sure if this was true or not. My cars isn't running bad or anything, but I normally change plugs every 30k. I have changed them once since I bought the car, which was roughly 25k ago, about 1.5 years. It has a full 3" exhaust and cobb ap tuned to stage 2.
But don't try to regap iridium plugs. They are very fragile. I actually would not recommend iridium plugs. They're fine, but a waste of money since they foul up just as fast in most of our cases.
Dum dum...I was told from the dealership that my STI probably has platinums. Though, I'd trust most people on here before them. I just wanted to say that's what I've been told. They said the plugs don't need changed until 60k intervals because of being platinums. Hmm...interesting.
Platinum and Iridium are both very hard materials comapred to copper.Iridium is slightly harder and has less resistance than platinium.Less resistance = better conductor.Copper has the least resistance of both but is much softer = much more frequent changes.Most dealerships I have encountered required me to educate their "techs".I am by far not the brightest bulb in the bunch but neither are most dealership techs for some odd reason.Many of my friends have had "tune ups" from the dealerships for their WRX's coming back with crappy gas milage and idle.This was due to the "techs" installing the incorrect N/A 2.5L plug in them.
Not to make fun of you at all Tumic, but you used that operative word "probably". Meaing: "I dont know what the hell Im talking about." Lol. I would believe may a people here before a stealersip.
I know, but i'm just looking for clarification newtothegame or for someone to say they have this and show me why. A lot of people on here are good at backing up why something is what it is.
Yeah, really mosc. People haven't been handing out a lot of rep lately. Though, i have been the recipent a few times lately. I'll rep dumdum, even though he probably leads the boards in rep. Haha.
Edit: It won't let me...I must've rep'd dum dum lately. Always next time. !Thumbs Up
Lol, my bad man. I know that there are better and worst places. Nothing meant by it. I really like my dealership I go to.
