yea i just went through another tank... 22mpg AFTER replacing plugs. Belt has been changed @ 100k (24k ago). Cap rotor and wires are next. I think i should just keep my foot off the floor LOL GSR with intake vs. 05 nissan sentra SE-R Spec V on 18"s is a damn close race. He gets about 1/4 car off the line and then we're neck and neck up to 100. Crazy ish.... damn 6 speeds! haha
