what size hex key do you need in order to remove the IM from the blower itself? There 2 diffrent sizes, one is pretty big, like a 8mm or something. but i have to go buy them on a socket, and id just like to get the right size the first time

 

those are 6mm bolts. the instructions (mine anyways) said 8mm on JR. however there is an 8mm hex bolt on the bracket i belive. but the blower bolts are 6mm. you mentioned buying a socket....just make sure the socket's outside diameter isnt too large to fit through the access holes on the manifold. i just ended up using a long allen wrench.

good luck
