Exhaust Nut T1N ONE

This listing is for ONE exhaust stud nut for the 2002-2006 T1N motors (both OM612 and OM647). You need eleven of them if you are going to replace all of them. 
We at MMS highly recommend replacing the exhaust manifold gasket if you are experiencing any kind of leak at the exhaust manifold. No need to spend all that time removing and replacing the manifold, only to find that the gasket is leaking too!
