How hard to change plugs and wires on LS1?
How hard to change plugs and wires on LS1?
Wanted to do new wires and plugs soon and was curious on how hard it actually was on the LS1? I remember on my 95 TA a shop wanted to charge like $600 for a full tune up..... Anything else you should suggest changing once i go on in there. Plus opinions on what plugs/wires to go with?
Not hard to do, just a little time consuming especially the first time you do it. Definitely not worth paying someone else $600 to do it. Take your time, prepare for bruises and cuts because they will happen. And yes the #8 plug will be a PITA, take your time, go from underneath. http://www.installuniversity.com/ins...sity/index.htm That link has a write up on how to do it. On the left hand side click on Install Documents, scroll down to the Engine section and there is a link for Spark Plug and Wire Swap. Helped me the first time I did it. Good luck. Oh, and I went with NGK plugs as well.
If your left fore-arm isn't too big (you know, if you're not the 'roid-rage type
) then you can pull all the plug wires, up to and including #8 from up top (I'm talking about on the passenger's side). Plugs 2, 4, and 6 will also come out from up top "easily"
. #8 plug (and plug boot) are best done from underneath. I just recently had to change the exhaust gasket on that side (forgot to re-snug headers ... blew the gasket
) and I tried doing EVERYTHING from up top. I *thought* I did really well, until I road tested the car, was getting EXTREMELY bad "popping / banging" noises out the exhaust, realized the engine had a bad miss, and it was because #8 plug boot wasn't fully down onto the plug!
(had to jack it up and push it on properly from underneath
).
Realistically, especially considering it's your first LS1 plug/wire swap, I'd plan on ~2 hours, although you could be done in about ~1hr if you're quick. 20 minutes??????
Sorry, but this isn't a 1st/2nd/3rd-gen you're working on!!!

I'm the anchorman when it comes to plug changes, 4 hours is fast for me.

I needed 90min for the first time.....
remove the A.I.R. pipe from the exhaust and you have enough room to work.
I removed the driver side coil rack from the valve cover too....
Plugs: DELCO Iridium (41-985)
wires: Autolite
works great for me!

It took me about 45min to do it when the car was Bone stock ( i have fat hands ). I added headers and cut the time it took by about 15min which ended up being around 30min. Now that i have no A/C or heater core it takes me 15min to change the plugs ( So easy ).

I used Moroso Blue Max wires and Bosch single plats as I dont want to do it every 30K miles.
One thing I will say, it is a lot easier than what people have said..
I made a post about it. Detailing the time.. use the search feature..
I didnt get anything special in the tool dept.. just had to climb on the engine and lay on it..
