Ignition Coil Replacement

Every time I try to buy a new coil online the dealer wants me to buy four. I was wondering if it is OK to replace just one coil or if I should replace all of them. Any help would be greatly appreciated. Thanks. Edited by Tom W Clark on 08/02/08 - 1:16 PM

An easy way to check them is to mist them with a water spray bottle while the motor is running. If they have hairline cracks they will arc to the block.
