I am looking to get a UR ultra S crank pulley for my civic... i have caught word that it can cause your Service Engine light to turn on at random points. Do you all know anything about this or any other problems caused by a crank from UR? thanks

 

i have a megan racing one and has had no problems since i installed it,,,, and no check engine light or anything has come on

 

do some searching as this has been covered.

Crank pullies are bad!
