I have changed a few spark plugs on the Taurus and the various engines and years. I have people go to the Ford dealer and get the Motorcraft PP for their engine. Because, I tell them the biggest cost is the labor to change them and since this is likely the last time you are going to change them (most of the cars have 80k+ on them), you might as well do it right and do it once along with the OEM wires ($80) instead of chasing down driveability related problems the next three to five years.
I tell them if they want to skimp, do it on regularly changed items such as the fuel filter and air filter which should be changed every 12 to 24 months.

Has anyone changed the plugs on a 3.0 Duratec V6 (24v) in a Taurus? My 99 wagon has 90k miles on it...still runs BEAUTIFULLY with the original plugs...but I want to change them soon. Do I really have to remove the intake to get to the 3 rear-facing plugs, as I've read?
Thanks,
Scott

ticking noise gone
thanks for the reply. The wrong plugs i put it were hot plugs high performane Bosch plugs and it was over heating the combustion chamber i guess is what i was told .the engine was not over heating guage there was fine(weird) but i was getting heat from my vent. I started to get this fine ticking from what sounded like coming from speaker atop driver dash. My voltage gauge was only showing 2 bars usually has 5 I put the right plugs in and heat stopped voltage gauge went back to 5 bars but the ticking noise was still there increased with acceleration. I found out it was my distributer\roter was fouled. cleaned up and noise gone. The lesson here dont try and put something wrong in your vehicle thinking it's going to make it a race car.
