The LF BPV features a piston o-ring seal that is twice the diameter of the old XLE design allowing more seal compression and reduced wear. Not only is this the best safeguard against leaks, but in the unlikely event of an o-ring failure, o-ring sealing allows the unit to be easily rebuilt. Adjustability of spring seat is no longer needed due to the updated spring and seal design which provides a 60% increase in clamping force at peak boost while maintaining similar operation at idle and transient loads.
