How does your car benefit from changing spark plugs? My car has 63,000 miles on it and the stock spark plugs... I have heard they don't need changed until aournd 100,000 miles. Is this true? oh, and what are the best spark plugs for a V6?

 

Spark plugs are like tires they wear out and need to be replaced. This whole you can get 100k out of plugs is as ridiculous as getting 100k out of tranny fluid. Sure you can most likely make it that far, but the performance, mileage, wear is going to be bad.

You need to change your plugs with 63k on them for sure. Best plugs are the cheapest ones. I am a NGK fan or Autolites work well too. Both are very cheap and do the job. Any autoparts store can hook you up with the 6 plugs you need to swap them out. Just don't be fooled into buying expensive plugs they will not make your car faster. Just good old cheap copper plugs perform the best and are the cheapest. Only downside is you change them more often.

Because I spray my car I swap plugs around once a year and sometimes 2 times a year if I melt a set while on the bottle. Which has happened 2 times on my car.

 

yeah sparkplugs are good to keep changing and deff get the cheap ones but i like to get motorcraft thats what the ford company uses...

 

Autolite 645 Coppers. I think thats the right number but thoes are the ones you'll want. Change them every 15K miles or so. Gapped at .054.

 

Awesome! Great information, fellas. Thanks for the help!

 

i made the mistake of getting bosch platinum +2's... THEY SUCK!!
