What plugs should I get that would work good in my 2002 Ford Escape V6? Any particular coil that has worked good as well versus the $90 each one at NAPA?

 

Motorcraft from Rock Auto.

 

I would go with Motorcraft plugs, but withhold judgment on paying for Motorcraft coils. Some have done will with coils from Amazon or eBay, and a full set is less than one M'craft coil. Wonder where the M'craft coils are made? Hecho in Mexico or hecho in China? Wanna bet?
Do a search of this sub-forum for coils and you will find more information. I have found some sources to be more customer friendly than Rock.

Thanks tom for all the help on my questions on plugs, coils and my cat question on another post.

 

If you have a misfire due to multiple bad coils, it may have a damaged coil driver in the computer. I just went round and round with one of these, it's a common issue. Replace all the coils, all the spark plugs, and if it still has a misfire replace the PCM. If you replace the PCM before replacing the defective coils, it will fry the new one as soon as the key is turned on.
