$659.41 $824.02
$659.41 $824.02

Fits BMW S65 and S85 engines typically found in the E90/E92/E93 M3 and E60/E63 M5/M6.

This Supertech Beehive Valve Spring set is engineered to improve valvetrain stability and harmonics in high-revving BMW M Power engines. The beehive profile features a reduced top diameter, which significantly lowers the reciprocating mass of the retainer and the spring itself. This design allows for better control of valve motion and reduces the risk of valve float at high RPMs.

These springs are specifically developed to be a direct performance upgrade while maintaining ease of installation. They are designed to work seamlessly with your factory BMW retainers and spring bases, eliminating the need for aftermarket hardware conversion. This kit provides a complete set of 40 springs, enough to fully service either the S65 V8 or the S85 V10 engine.
