Default Spark Plug change question

Hello guys,

I have a noob question. I'm at 70K miles in my 08 IS350 and about to change my spark plugs after I noticed some symptoms of worn or wearing spark plugs (rough start and idle, sluggish acceleration, black deposits on exhaust tips). I know I was supposed to do the change at 60K, but i was caught up with school and forgot about it.

Anyways, is there any other things that I should do tune up wise with this spark plug change around this milage or anything I should know? Ill probably be buying the plugs off of sewell and following the DIY on here to change them. I recently changed the oil, cleaned my air filter and MAF sensor. Any advice would be awesome.

Thanks in advance.

Sounds like you did the other stuff already. Get those plugs changed, you should feel a noticeable difference. Are you using premium fuel?

Only other item you should do is the brake fluid as stated above. Needs to be done every 30k. As a side note if you plan on diy'ing and keeping the car for a while I would get a set of speed bleeders. Makes it a very quick and simple task.
