You cannot touch L19 with your bare hands or the oils from your fingers will corrode the studs. CA625+ material is just as strong, offering an increase in clamping force, without the difficult-to-deal-with issues that L19 has. These CA625+ studs will allow you to run even more boost without the head lifting, and will ensure the longevity of your engine even more.
