Diy spark plug replacement 3.6
 
Can anyone answer my question if the V6 pentastar engine and the v8 can use the same spark plug replacement writeup. are they in the same location?

No. It is necessary to remove the intake plenum to gain access to the plugs on the driver's side of the engine. It is however a "coil on plug" based system just like the 5.7. But, the spark plugs are a 12mm (smaller than the common plug) which requires extra care when tightened down. Overtighten them and a severe heache can occur.

....and there's only "6" vs. 16 in the Hemi.

Once you get the intake plenum removed, it's gravy. There are 2 bolts on the rear/passenger side of the intake that are a bit cramped to get to. The 2 nuts on the driver's side of the intake where the plenum is secured to the support bracket are best removed with a gearwrench/ratcheting wrench. After the nuts are removed that secure the lower part of the plenum, you will need an eTorx to remove the studs. Or, you can choose to remove the bolts at the bottom of the support brackets and make a moderate skin sacrifice to the car gods.

It used to be that you could change simple things like headlight bulbs, spark plugs, etc. without having to donate skinned knuckles to the cause. I'm pretty sure that car designers have since formed an unholy alliance with the car gods. After all, the Car gods cannot go without their blood sacrifice... :eek:

How do I get the intake plenum off? I pulled the two nuts on the drivers side, the one nut on the passengers side and removed the 4 screws on the top. I can't get the plenum to budge. Any tips or pictures would be greatly appreciated. On the drivers side of the plenum, I got the front bracket loose but I couldn't get the back bracket loose, there was a strap from a tube over the bolt. Even without loosening this, I could not get the plenum to budge, I'm assuming I missed a bolt or two, but I can't find or see them.

Please help, I don't want to take it to the dealer.

There are two 10mm nuts behind the throttle body. you can see them from the passenger side. It may be easier for you after you remove all the nuts, to grab an "e-torx" socket and remove the studs on the side of the intake plenum as well.
