AMS is now an official supporting vendor on benzworld! We would like to celebrate by offering a special on our crank pulleys. The first 5 that order the pulley will get a free AMS T-shirt with their purchase. We just finished a new batch of pulleys for the W209s and they are ready to ship. For more information regarding our products you can click the M113 link below in our signature. Thanks
EDIT - since posting this message it has been reported by various owners of the AMS pulley that it has failed or caused other problems and they have since removed it. Hooleyboy for one no longer has it installed, despite originally being very pro AMS pulley.

at the prospect of an easy >10HP and 3mpg gain - but there is no free lunch.
Let alone paying $500 for shiny new pulley which does next to nothing.
Of course if you want to test it and find out for yourself I'm sure AMS would be pleased to oblige - heck he even offers a 'money back dyno guarantee', but make sure to read the small print first !
