Not on an 04 it doesn't. 98 in the grand's and about 00 in the cherokee and wrangler they went to a one piece coil pack set-up with 3 coils all mounted in a large pack that bolts to the head right over the top of the plugs. Just make certain to only use the correct CHAMPION plugs in them as I can't tell you how many of em I fixed by simply changing the plugs out when people would put in bosch or NGK.
