SO anyone know how to get at the spark plugs on a 2007 Civic LX? It is not as easy, as my 2000 EX. Anyone have photos?

I have about 30000 miles and want to put new ones in or at least check them, i dont see wires even?

it doesnt use wires, just coil packs. its those four ball looking pieces at the top of the engine that are held on by a screw. just take the screw off, unplug it, and pull out. plug is inside. you may first need to take off the top plastic cover.

how do you take the plastic cover off?

usually its just twist clips, turn them 1/2 way counterclockwise with flat screwdriver

on my 2006 it was a squeeze and pull kind of clip to take the clip off once u had taken the bolt off and then the coil pack just slid right off. Make sure tho that with putting new spark plugs in that u have them gapped all the same and correctly or else it will start causing some problems

I bought some plugs online from South Bay Honda (Hondapartscheap.com, I think it was), and an Air Filter and Cabin Air Filter. I have 53,500 on my '08 LX Auto Sedan. Plan to wait until just prior to 60,000 for the Filters. I pulled the Plugs last week. None of the 4 needed to be changed, so I put them back in. The plastic clips were a breeze. Just push DOWN on the back of the slide-on clip, and pull it backwards towards the plastic cover where the wrapped wires coming out of the clip disappear into. The little HexHead Dome Nut on the Left side of each of the Four Boots (Plug Hole Coil is th official part name) is 10mm. They (Coil) are right in the front of the engine, almost right on top, but a little towards the front, right in front of the plastic cover over the top of the motor/valve cover. Can't miss it, even if the engine is dirty!! Turn the nut counter-clockwise to loosen, then it comes off in your fingers. The Boot/Coil pulls upward, and mine came out with no fuss at all. You are supposed to change Plugs when the engine is completely COLD. I think it has to do with the aluminum head expanding/contracting. I drove 50 miles to use a gearheads eye. Car sat for 4.5 hours. It wasn't over 60 degrees out, and colder when I got there.
The plugs did not come out easy. Had to get a bar and put it on the handle of the ratchet for leverage. Was super cautious to keep from yanking on it when not squared up; legs spread wide apart, leaning over the engine, right hand rigid on the ratchet head, etc... The treads had places of rusty dust on them. The threads in the head looked brand new, and the iridium tip of the plugs almost did, too.
I put anti-sieze on the threads when putting the plugs back in, and also dielectric grease on the ceramic part of the Plugs (just a dab) and a dab in the boot/coil.
Did not use a torc wrench, just snugged them down. I've done lots of plugs, though never in a Civic, or an aluminum head.
Good learning experience, and I'm 99.99% sure everything will be fine and they will come out and go in with no problem when the right time comes down the road.
