Now that I am buying a 2.55", I am gonna be putting a new cat on, and getting colder plugs. What plugs are recommended and what gap? And also, anyone within Ohio, IN, PA, or MI with a scantool? If so, Maybe I can drop by at your house and we can take a look at the KR before installing the pulley?
EDIT - The EM'* are only 2 years old and are crackless.
