    Description

    BMW Performance Valve Springs - M57 M57N M57N2 M67 and M47 engines
    Performance Valve Spring Kit for BMW 8
    Cylinder,
    6 Cylinder and 4 Cylinder
    Diesel Engines
    The springs are compatible with all the m57 engine variations
    The set prevents valve float under
    high boost pressures
    due to springs greater stiffness compared to the OEM springs ( +35% )
    M
    57 has really
    weak springs from factory
    .
    This causes these engines to stop power production with higher boost pressures , issue gets worse with more boost and exhaust manifold pressure.
    If the valve springs are weak, the springs may not be able to push the valves all the way shut before the next opening cycle begins. If the valves fail to close, the cylinders will lose compression causing the engine to
    misfire and lose power
    . In some worse situation
    Pistons can also hit the valves
    Sold till now only on the Bulgrian tuning market from over three years with zero complaints.
    They are
    d
    irect fittment and require no machining.Tested at over
    3 bars of boost pressure
