Schrick High Performance Valve Spring Kit, BMW S65

Engineered to replace BMW part numbers 11347837681, 11347835154, and 11347838295, this new set of valve springs and retainers meets the demands of high-performance engines. It is designed for the performance camshafts in your E90/E91/E92/E93 M3 equipped with the S65 engine.

The set includes:
32x valve springs
32x titanium upper retainers

The Schrick S65 springs feature a single-spring design with a revised rate, making them superior to stock springs. These new springs are stiffer to prevent valve-piston contact with the extra lift from these cams. The top retainers are made from titanium.

 Installation requires the expertise of an engine builder.
