The 4.0L 6–cylinder engine uses a one-piece coil rail containing three independent coils. Located on the right hand side (passenger side) of the engine.

The one-piece coil bolts directly to the cylinder head with 4 13mm hex bolt (M8X50). 3 of the bolts are immediately visible.

The fourth one is somewhat hidden in the back, under the coolant lines for the heater. The hoses can easily be moved out of the way.
