Genuine Victor Reinz torque-to-yield (TTY) cylinder head bolt set, engineered to OE spec for BMW's N54B30 twin-turbo inline-6. These single-use bolts stretch permanently into the plastic region when torqued — they must be replaced any time the cylinder head is removed, and should never be reused.
Fits: BMW N54B30 — 135i, 335i, 335xi, 335i xDrive, 535i, 535xi, X6 35i, 740i/740Li, 1 Series M (1M Coupe). Also commonly listed for Z4 sDrive35i and 335is — confirm your engine code is N54B30 (not N55B30) before ordering, as some model years of these platforms switched engines.
- Head Bolt Set — complete set of TTY bolts for one cylinder head installation
⚠️ Always replace head bolts as a full set whenever the cylinder head is removed — do not reuse old TTY bolts.
