I own a 2000 ford mustang, with 130,000 Miles. How often should i be changing my spark plugs?

I agree with DEE but I have used and liked Bosh platinum for years, much better than Motorcraft. I have tryed a set of the new E3's an like the results also!

The answer should be in the cars owners/service schedule manual.

Spark plugs are rated for every 100,000. Under severe use 80,000. (severe is like towing, racing, commercial transport, plowing, etc).
If they are the original ones - replace them. you won't regret it.

But stay with Motorcraft !!!!
Platium III last pretty long, but I would replace it. Agreed with staying with Motorcraft only.
