i just purchased a 1998 SEDAN DEVILLE D'ELEGANCE
beautiful car..only needs a tuneup
i priced one at a shop they told me around 600
i priced factory plugs at orielys auto for 6 each and wires from 60-80

the motor is the 32 valve northstar
i see the front of the motor would be no problem to do the plugs but the back looks fun...what all needs to be removed in order to do plugs and wires

also where is the fuel filter located on this car?

Thanks in advance for any help.
