One of the twins drug a 97 Mustang GT home and it needs new plugs from the maintienence history I've be told about it. It's the 4.6L V8 engine w/100K miles on it. Any suggested type of sparkplug? Thanks.

 

Usracing guys likeNGK Iridium spark plugs.

 

Autolites also work well in Fords.

 

the use of spark plugs on vehicles is to create an electric spark that will initiate the combustion of the compressed air fuel mixture in the engine... that results to the full operation of your automobile. when spark plugs got defective, it emits black smoke... when i had that experienced, i installed mine with mercedes benz spark plugs, so that it will prevent the spead of defects to my auto.
