Before you begin
This is a relatively easy job, the fastening bolts are all located on top of the engine. The coilpack connectors are easy to disconnect without damaging anything, and the spark plugs themselves are not difficult to replace. Note: This service requires that the battery is disconnected, meaning that the factory radio will require its code to be reentered. Do not perform this service without the code, a dealer would have to re-enable the stereo's functions
