I did go to Pauls site and alot of those links and parts are no longer available..grrrrr. Everywhere I look is a brick wall. No wonder. I have to figure out my fuel economy issues this week anyway. Averaging roughly low to mid teens on hwy and city and not "on it" all the time. I am thinking there are issues. Plugs maybe??? All happening this weekend. Have you heard of any other underdrive pullies for the xf? Maybe I need to start thinking more mb? Looks like 2000-04 CLK320 and 01-04 SLK320/32? Correct? Any others? Someone has to make more for these cars. Pulling my hair out here. Ready to pull the trigger on more power but nothing to shoot for, lol. Never had this problem. Kinda like ED??? hahahaha
