I decided to change the plugs in my 2003 Santa Fe 2.7 V6 and much to my dismay found that the 3 plugs on the back side are virtually impossible to get to without quite a bit of disassembly. Anyone know of any way around taking off half of the intake system?

 

unfortunately no although you can do it keeping the pipes on the throttle body on.Easy way i find is to undo the bolts in the center of the inlet and the 3 bolts at the back supporting the manifold and it should give you enough clearance to get to the plugs(careful not to damage the ht leads)

 

Will this save the gasket or will I need to replace the gasket?

 

no mate you can re use the gasket.
