For the Accord EX V6 ...

On the Accord @ 140,850 miles:

• K&N Air filter is taken out (after close to 95,000 miles of use) and replaced with a paper filter. It seems like the oil from the K&N does clog up the parts in the intake (which happened to both my Accord and my old Corolla GTS)
  
• I also adjusted the tire pressure to 34.5 psi in the front and 31.5 psi in the back
