Are there any tutorials or threads that give any details on changing them or is it really pretty easy?

I'm new to engine modding, but it seems like you just unplug the sensor, unbolt the plug bracket, then I'm guessing you just drop them in and bolt them back in right?

Or is it more involved than that?

 

its really, easy, you have to take your strut bar, engine cover, and intake off. you'll need a 10mm for the bolts, a spark plug socket, maybe a 6" extension.

 

what's a spark plug socket? or what do you mean? like a wrench for it or something to hold the new spark plugs with?

 

A spark plug socket has a rubber liner inside that holds the plug in the socket for removal and placement. It's also deeper than your average socket.

When I installed my plugs, I didn't remove the strut bar, and only removed the intake tube itself, along with the engine cover. You will definitely need an extension, seems like mine was a 12" - those plugs are down in there. Quite a bit of moving stuff around to get to the coil packs (hoses, wiring, etc.) but all-in-all not a big deal...very easy. Seems like it took me about an hour my first time - start to finish. I've read of other folks doing it in 30 minutes or less. But I'm particular. ;-)

Also, if you don't already have one, get your hands on a good torque wrench - you DO NOT want to over torque any of the bolts or especially the plugs. Do a search for the torque specs (info's kind of scattered around on the site, but it's here). I can't remember exactly what they were and don't want to post any misleading information. Or better yet, buy a service manual.

Anyway, as I said - a very easy DIY.

Have fun!

also make sure they new sparkplugs are gabbed correctly and you don't accidently drop them and change the gab

 

mdacko. Maybe you could change mine since they are so easy!! just kidding.

 

It also helps if you disconnect the brackets that hold the harness in place, for me this made it easier to get the coils out as the harness was in the way on a couple of them.

 

how would i go about cleaning my spark plugs?? i haven't done this yet...i guess i will sit down for a day and do this when i get a chance...but is there some special cleaner i should get or what???

I was wondering the same thing. But I'm convinced that if I could change plugs on an LS1, I could change any plugs. Those who have changed plugs on an LS1 know what I mean
