Nope. Its as easy as removing 4 13mm bolts on the coil pack rail. Give it a gentle pull and comes up fairly easy. Keep one thought in mind, the electrical connector is attached to the end of that coil rail by the firewall. Avoid pulling it too much or it will damage the connector and possibly pull the connector pins. There is a red locking tab on that connector. Find the lip on that tab and pull from that lip with a small flat head screwdriver until the other end of the lock is flushed with the black connector housing. Pinch the connector release tab and it will come off from the rail. It's not nescesary to remove the connector from the rail when servicing the spark plugs but some prefer it that way.
