Thanks for the video, especially the 19 mm “hidden” bolt. Changed plugs while watching your video and kinda going slow to avoid a oops or two and finished start to finish in 2 hrs. 17 minutes. Shop wanted to bill me for 3.5.
For those asking if you need to change the upper intake gasket – YES. As soon as you move the plenum you are likely going to tear/break the factory paper gasket that is now hard and brittle. Just carefully remove all the variouls plug ins surrounding the plenum except for the fuel line (located on the top front left). The fuel line will pivot and allow you to move or rotate the plenum. Make sure and remove all the old gasket using a razor blade from the intake and the plenum.

Why don’t you check your turn signal fluid, and spark plug return valve…

When you removed the air intake piping did it have like a puddle of oil in it? Is that normal? 3.6 liter V6….
I have the same car with 115,000 miles on it, I plan on changing the plugs, but also the fuel filter, where/how do you change that?? TY.
Thanks
I like how he starts it out. If u can’t remove the cover then this ain’t for u

Thank you for your help. That back screw and the big-18 mm in the front bracket was a pain.
