A complete set of 24 exhaust studs and nuts from the N54 motor, these studs have an E-torx splined head so that they can be installed with a socket/spanner rather than having to double nut them on. The nuts have an internal Torx drive or can still accommodate a standard socket or spanner.
These are a great upgrade for M5x motors as they often pull out the exhaust studs and they are hard to get in M7x1.0 sizing without spending big.
