This is done to prevent the socket from falling off and getting trapped in the narrow coil pack tube, which would be annoying to retrieve.

Putting a wrong wire or in this case, a wrong coil pack on a plug, is going to make the engine run terrible or even not at all, so keep track of which plug goes on which cylinder. The coil pack is a collection of ignition coils controlled by your car's electronic ignition that transforms the power from your carsīattery down to the spark plug, which of course ignites the fuel and drives the pistons. On modern cars, coil packs are used in place of distributors and ignition wires because they provide more efficiency and reliability by using no mechanical or moving parts like distributors. Likewise, you can take a quick picture with your phone for safety. Remember to mark the location of each wire before you remove anything.

Lay a towel over the fender before you get started to protect the paint as you will be leaning over the engine for some time. Visit your local auto parts store to buy the plugs, but if they don't have the OEM brand, they can usually cross reference a suitable replacement.
