2008 Focus with 65K, time to change spark plugs yet?

I know the factory interval is something like 100K, but I was wondering when the majority of you all changed yours out?

My wife's 08' now has over 65K so I was thinking about changing them. Do I need new coil boots when I do this, or just clean the factory ones?

Or should I just let it go till it hits 100K?

Thanks,
Greg

The only sure way to tell is to pull them all out and look at them. Plugs are cheap, can't go wrong putting in new ones. Boots are the same way, depends on there condition.

I just changed the plugs on my 06 ST at 75000 miles. Runs like brand new and the gas mileage is 2-4 mpg better. Also change oil and fuel fliters to cover all the bases.

I change mine at 10k but I use Autolite 103 copper plugs. I also change out the boots about once a year or after 20k miles.

I don't understand why everyone feels the need to change the plugs at 10000 miles that is rather excessive in my opinion. I would just like to say that car manufacturers are not going to recommend a certain maintenance interval without having thought the matter through and after much real world testing. If the manual says 100000 miles for standard usage that is what I'm going to do my money and time are much to important to be worrying about such mundane things. I have an '03 with 80000 and an '07 with 50000 both run great by following fords schedule.

My advice is still to just pull them out and have a look at them, the '01 Ford Ranger I had before my Focus had the same 100K plugs but they were junk by the time I hit 50K. Looking at them cost nothing more then a few mins of your time and can help you to shot other more serious problems like leaky valve stem seals and what not.

Does the 08-11 models even have spark plugs?

Changed out the ones in the ZX3 at about 90k miles and got about a 2 mpg increase in fuel economy. The 100k plug change out that so many vehicles have gone to is part advertizing ploy and part better technology.
