Changed plugs today and it went smoothly. Great write up. Plugs and filter cost me $80.00 canadian. Glad I have different extensions and tools to do the job.

Thanks

Re: HOW TO: Change the Spark Plugs on an 07 WK 5.7L

Regarding this statement - "You DO NOT need anti-seize for the Champion copper core plugs, Champion expressly states this, their plugs are coated already."

I checked out their website and found no mention of this. The 570 plugs I installed showed no signs of any anti-seize properties on the threads, so I used some.

Too many memories of pulling the threads out of the aluminum heads along with a seized plug in my old VW bugs!

Thanks much for a great post. My first plug change on this vehicle went flawlessly due to your excellent report!

Re: HOW TO: Change the Spark Plugs on an 07 WK 5.7L

Thanks TheAngryMinnow,

It was a great help having this write up, It helped me a lot!

Today I bought 16 Champions 570 plugs, $1,99 each @ Auto Zone, it took me around 2 hours and a half to perform this activity, I can tell you for sure that cylinders 1, 3, 8 and 6 are the worst one to work on, man what a pain...! seriously this engine sucks for serviceability.

I'd checked all 16 plugs and they did looked good, however i realized that cylinder 3's plug did had a nasty gas smell but it wasn't damped, any thoughts about this? I also realized that the coil's bolts weren't so tight it was loose actually.

While doing this activity I took the chance to inspect the TB and I found it was extremely dirty, had to take it off used some breaks cleaner, I took some pictures.

Now the big question is, will Sea Foam be enough to clean the whole inlet manifold? what do you think guys?

It will probably clear out SOME of the carbon build up in there provided you do the treatment through the brake vacuum line. However, the only real way to get ALL out would be during a port & polish, and removing the upper intake manifold (always risky and may involve cracking and/or milling later). The vacuum line treatment should be good enough.

Re: HOW TO: Change the Spark Plugs on an 07 WK 5.7L

Getting ready to change the plugs on my 2011 wk2 and hoping it will look similar, if not the same. I can't seem to find any write-ups for the wk2.

Anyways, thanks for taking the time to write this guide and include pics.
