Default Spark plug replacement interval on 03 WRX?

Someone confirm this one, or at least agree or disagree with me.

Everything I've read says I need to swap my plugs at 30,000 miles. Right now I'm at 30k miles.

Monday I took my car into my new Subaru dealer who did not change them. I called them today because I was in a hurry, and the service advisor said that WRX "plugs are platinum and get changed at 60,000 miles. You only change the plugs at 30,000 if you're driving a non-WRX Impreza". I was going to do this work myself, but frankly don't have time to learn how and do it.

Help!

Okay, then why does my.subaru.com list a plug change at 30k miles? If they set the maintenance schedule, then why are they incorrect?

So confused

that's for non platinums...

take our "bit outdated" but near accurate list on allsbuaru.com

http://www.allsubaru.com/schedules.html

30k states:
Change spark plugs (2.5 L and SVX at 60,000 miles)


ya see the Phase I 2.5L's were DOHC, thus they were Platinum
(SVX's are also plats) - our list needs to be updated


WRX 2.0 would fall into this category - 60k
any subaru w/plat plugs are swapped at 60k

any non plats = 30k

I also find out that my.subaru.com is inconsistent with the owner's manual. For instance, it recommends the first oil change to be at 3750 miles, instead of 3000 miles on the owner's manual. I refer to the owner's manual instead.

And yes, 60k for WRX plugs. They are platinum.

Heh, they BETTER be platinum... Otherwise someone's goinna have some 'splainin' to do...

But yeah, 60k miles... I'm happy for that too because they're going to be a real biotch to get to...

Stock spark is platinum. The recommanded maintenance interval is 60k miles. However, depends on your driving habbit, the gas you use and the kinds of modification on your car the change interval might vary. If you are running high boost then usually a coder plug is better, I am not sure how much it will wear out the stock ones. If you are pushing your car pretty hard constantly then I don't think keep that plug for 60k miles is a good idea.

I plan on chaning the plug like 40k or so. They are not that expensive after all and only takes me about 30 mins to change them.
