Yo, do you even listen to the radio? Cuz if you don't, I have a solution. I just removed mine a week ago (it was having problems, too) and rigged up a little system. $0.45 and a trip to Home Depot will buy you a low profile round head bolt and a nut and washer. Prime and paint it with touch-up paint and you've got a clean lookin' plug. (Check out my thread on page 2, I think, if you want the whole story.) But if you need those radio waves flowing...ouch....having the warranty helps, tho.
