I got the Bosch platinum plugs, Autozone said they were factory replacements. Since I don't trust the parts people at those kinds of stores, I double checked online and confirmed it. As far as I could tell, none of the vacuum lines had any issues. The only thing I'm unhappy about is that I had to stop in the middle of the job. Not only that,but stop overnight and pick up 24 hours later. I always hate having to stop because I get in a groove and remember everything perfectly, etc. Oh well. Hopefully it'll be done in a couple hours and back on the road in like new condition tonight.
