Head Bolt Set, BMW - E82 135i, E9X 335i, E60 535i, F02 740i, E71 X6 35i, E89 Z4 35i, N54

Head Bolt set for the cylinder head on N54 engines in E82 135i, E9X 335i, E60 535i, F02 740i, E71 X6 35i, E89 Z4 35i.

New head bolts are required any time the head bolts have been loosened or removed for any reason. They stretch when properly tightened so re-using them again will not tighten the head and gasket all the way. Set includes 18 total bolts - 1 x M9x30, 3 x M9x70, 4 x M9x125, and 10 M11x135.

This is a Genuine BMW N54 head bolt set with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
