I like to keep my car maintained as much as possible,so I plan to replace the spark plugs on my '06 Civic, my question is how hard is it to replace them yourself?I know older cars it's had because they are buried,but from what I see the spark plugs on the Civic are right in the front...
Would it be fairly simple to replace them myself & what tools would I need?

(P.S. what type of spark plugs should I get,I heard there are premium ones that spark much more and improve efficiency,where can I get these/what are they called?)
