This convenient kit includes all the hardware you need to replace your old, rusted (or broken?) exhaust manifold studs on your M50-family engine's head (including M50, M52, S50, S52). The perfect time to preventatively replace your exhaust studs is anytime you remove the manifolds (perhaps to install headers) or are removing the head or complete engine. Kit includes the correct number of OEM studs, copper locking nuts, and also includes two jam-nuts to be used for removing your old studs and installing the new studs. This stud and nut kit Fits 325i, 325is, 328i, 328is, 323is, E36 M3 (3.0 & 3.2 liter), E34 525i (91+), E39 528i, Z3 2.8.

These studs will save the day! Stripped or corroded exhaust manifold studs are a major pain to deal with. Rusted studs fuse themselves to the nuts and back out of the cylinder head. These are M6x35 stainless exhaust manifold studs with new copper nuts that will make your manifold install a breeze! These studs have an internal 3mm hex so no more "double-nutting" or stud installers are needed, so no more galling threads! These have been a best seller for us since the late 1990s!

These are M6x35 stainless exhaust manifold studs with new copper nuts that will make your manifold install a breeze! These are a best seller for the E30 M3 and we put together a similar kit for the S38 in the E34 M5 (earlier M88/S38 use a different length stud). These studs have an internal 3mm hex so no more "double-nutting" or stud installers are needed, so no more galling threads!
