or just pull it off with your fingernails. worked for me. didn't need any of the high speed low drag fishing line, or string or hair dryer or lubricant.
ok, before you do this, i have an '06 and i took this off to get rid of the "3" and just leave the mazda part. And it was a good thing i did because there were two pegs in it to make sure that it was stuck on correctly. As well, i would not suggest using your hands. Use fishing line and a hair dryer. It works a lot better.
