Winfred and Bill R.: You guys seem to rave about this plug so I thought I'd give it a try. Went to Kragen to special order these and the guy tells me that each plug is $24.99!!! What!!! "It's a high performance plug," he says. I'm looking at the receipt as I type this message just to make sure my eyes are not playing tricks on me. Is this guy taking me to the cleaners?
