A can of Liquid Wrench and a BIG-ASS Vice Grips. It takes a bit of work but they will come off. Just make sure to cover your TB opening so that any crud/metal shavings don't get into it.

BTW, I put mine on about a month ago and am now having some problems. It bogs down when I stomp on it every once in a while. I'm going to try cleaning the MAF. I think that some of the oil from the filter may have gotten on it. Any other thoughts?

HTH,
Ben
