Depending on how old your engine is ..................
Pre 2002 ish there was less gaps in the front manifold, so I tend to remove that type.
Later types can be done just by removing upper manifold, and then working through the gaps
Someone's done it just by removing the throttle body and struggling around through the "side Gap"
I get back ache doing that and it's only 20 mins removing upper one!
Later type below
Note the swimming pool of OAT in this one !!
