So I guess, with my car being at 51000 miles I should probably change the spark plugs...? And maybe the PCV valve?
I change my oil every 5-7 thousand miles, I use FULL synthetic.

Yeah, they look good, but getting the old ones out was quite the ordeal with the STB, so I wasn't going to put them back in, only to take back out in another 5k or so. Maybe it's my imagination, but my butt dyno felt a huge power increase.

A true power increase will also be reflected in better mpg, if you continue to drive in the same way that you did before without using the "increased" power.
It's not the same power increase you get from washing the car or changing the oil, is it?

Re: Spark Plug Change
10. Once the plug is screwed in you can use the torque wrench to tighten it to 13 ft lbs
-or-
after it's hand-tight tighten it 1/2 a turn more.
I bought bosch platinum+4 and it sais 21 ft lbs. Do different makes of spark plugs get different torque? Does using anti seize compound affect the recommended torque? I was confused and needed to use the car so installed mine doing 1/2 turn witch was 18 lb. Did I hurt anything? should I adjust it and if so to what?

I always use anti-seize to avoid problems. My brother was once unable to get a dry plug out of the engine, afraid he was about to ruin the threads, had to leave it halfway out and run like that until he took the car to a shop.[/i]

Just changed my xB RS 1.0's plugs to NGK Iridium iX-11 with the .044 gap...
Everything went smoothly, works fine. Was a little scared when I started breaking the old plugs free. Don't think the dealer used anti-seize on the first replacement.
Can't believe I didn't do this sooner.
Great write up!
