Changing the oil

I'd like to hear some of those so I don't make the same mistakes if I have to remove my plugs. I did one side once just to check them and it was alright, I didn't bother with the intake side. Talking about spark plugs how much mileage you guys think I can do with my stock ones. I have 99000kms on my car now.
 
Our engines are VERY picky about plugs it seems. Make sure you check, recheck and double recheck that they are properly torqued (!!!!!!!!on a cold engine!!!!!!!!!) to see that they aren't backing out. If they aren't torqued properly the 4.6's like to blow plugs out which can cost a pretty penny to replace.
