E46 M3 Schrick 280 Degree Exhaust Camshaft with 14.0mm valve lift. This is only for use in professionally-built E46 M3 race engines. Schrick has developed this ultra-aggressive S54 race cam with 280-deg duration and 14mm of valve lift. Because of the aggressive profile and specs of this cam, Schrick only recommends it be used with special custom pistons with deep valve reliefs.

Schrick valve springs
Schrick rocker arms
Schrick upper and lower retainers

BMW cylinder head bolts are almost always stretch bolts and should never be reused after removal. Reusing old bolts can lead to a weak seal between the cylinder head and engine block, allowing the head to lift and cause potentially catastrophic damage. Replace your old cylinder head bolts with these brand new Elring bolts to ensure your head is properly secured to prevent damage and keep your engine healthy. Replaces BMW # 11128513128
