2005 Outback 2.5i spark plugs

Pulled the first plug out, it's a NGK R FR5 AP11
Are the new plugs incorrect? They are platinum. Is that the difference.
Wanted your opinions before I slap them in there as if they are not correct they are going back to PB.

How many miles do you have on the plugs? The platinum plugs will last quite a while.
You can find out more info on the plugs from NGK's site.

I jsut installed the "laser Platinum" second set in the GF's car. They are called double Platinum on the NGK website - which also calls for the wrong plug. Website calls for a 10, Dealer and old paper manual call for an 11 - which means wider electrode it seems.
In that late model of a car I'd bet you want the "laser platinums" I know a 2006 calls for them.
The regular old green writing BRK's I use up to 2001 or so. Unfortunately I have a gap in experience between 2001 and 2006.
If you want the info on what I got just PM me. I have the documentaion on another computer and can look it up.

Also discovered a lose plug wire that explained my wife's description of rough running at a stop. Runs fine now. I had to order plug wires but may just save them for my Legacy, which is about to turn over 50K. It's an '09!
