Product Information

PAC Enhanced single valve springs for the Toyota B58 3.0L, sold as a set of 24. Seat and open pressure set how firmly each valve is held shut and controlled at full lift, which is what keeps valves from floating at high rpm. They need Ferrea titanium retainers and hat seat locators to fit, all sold separately.
