Tune Up on 2004 Santa Fe 2.7L V6
 

I'm trying to figure out if I have to take the manifold off the top of the engine to get to the back 3 plugs... Can someone please help me?? Thanks

Yes. The upper intake manifold (AKA surge tank) has to come off.

That's a bummer is what I say...but oh well that's what you gotta do to get the work done..
