I have a 99' prelude that I bought used. I took it in for the 60k service the other day and they told me someone had replaced the stock plugs with some regular autolite plugs.
They asked me if i wanted them to put in the factory platinum plugs for $90.
I told them not to worry about it, since I wanted to do some reaserch to figure out what might be the best plug to get.

So i have 2 Q's for everyone.
1. can you recommend a good plug to go with or should i just stick with oem?

2. Has anyone changed their plugs themselves and if so did they use a tourq wrench or could i just hand tighten them plus one turn?
