at work we recomend at 50k miles (after your 100k service we start over again):
air filter, fuel fitler, trans flush. if your coolant wasnt done at 100k it should be flushed, brake fluid flush (millage based), power steering flush (millage based).
hey jlw. i got back to you on shipping.

Tranny and coolant flush was done in May 2010, power steering return line had a leak that was replaced this week so it's new fluid and recently did the camaro front brake swap so its new fluid as well.
As for the o2 sensor, i'm just think that maybe it'll help a bit because I'm getting about 22 MPG on the highway and I thought I'd give it a shot.
Edit: as for fuel filter it was also changed in 2010, but I'm going to replace it soon again. And for the the air filter according to
www.fueleconomy.gov some new study shows replacing a dirty air filter only restores power, not performance. I'm still going to buy a K&N cone filter to replace this shitty generic filter I have on my cold air intake. The MAF and TB were also cleaned this year as well.
