Pack of twelve M8 copper-plated exhaust nuts intended for BMW 3 Series E30. Carbon steel construction with copper plating aims to improve durability and resist corrosion in exhaust environments.
Improved corrosion resistance – thanks to copper-plated construction
Copper plating over a carbon-steel core creates a protective surface layer that slows oxidation and surface corrosion when exposed to exhaust gases and heat.
Longer service life in corrosive exhaust conditions, reducing the chance of seized or degraded nuts during future maintenance.
Secure fastenings under vibration – with self-locking M8 threading
Self-locking design resists loosening under repeated thermal cycling and engine vibration, maintaining clamping force on manifold studs.
Reduced need to re-torque fittings frequently and a lower risk of exhaust leaks from loose nuts.
Straightforward fit for restorations – with OEM reference and compatible sizing
Listed as M8 nuts with a 10 mm internal thread diameter and genuine references A1201420072 and MPN 11621711954 to match OEM specifications.
Easier replacement and greater confidence that the nuts will match BMW E30 manifold studs during a restoration.
