MX5 NC ARP Head Studs (New) (Aftermarket)

MX5 NC ARP Head Studs (New) (Aftermarket) ARP Head studs are the go-to method of ensuring accurate and consistent torque figures holding your head down to the block. They install as studs rather than bolts and as such the head must be lifted on and over them during installation, this makes aligning everything far easier. They are re-usable and offer industry-leading strength, a worthwhile upgrade if you are building an engine to take ~14psi+. Features Compatible with L8, LF, and L5 variants Replaces factory torque-to-yield stretch bolts Reusable high-strength ARP fastener Improved clamping force and reliability To Suit: Mazda MX5 NC 2005-2015
