1997 Nissan Maxima changing spark plugs

I may have been given false info. The parts store guy told me that and I just assumed it was accurate, even when I opene dthe hood and glanced in. Went to take a photo and re-examined. It seems that the plugs are under some screwed down coil. There isn't even standard plug wires, just some wiring going to these coils. The coils are also located between the intake manifold ducts. That same manifold I assumed I had to remove. Thanks for your reply.
