What is the main benefit of upgrading to these Manley valve springs?

These Manley valve springs are designed to handle higher RPMs and more aggressive camshafts than stock springs. This helps prevent valve float, ensuring more consistent engine performance when you're pushing the engine hard.

Are these valve springs a direct replacement for the factory ones?

Yes, these springs are intended as a direct replacement for the factory valve springs in the specified SR20DE and SR20DET engines. Installation is straightforward if you are already performing an engine rebuild or valvetrain service.

What other parts are typically replaced when installing new valve springs?

When replacing valve springs, it's common practice to also inspect and potentially replace valve seals, retainers, and keepers. If you are using aftermarket camshafts, ensure they are compatible with the spring pressure.
