MX5 NA/NB ARP Head Studs (New) (Aftermarket)

MX5 NA/NB 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+. Installation requires a 1/2 12pt socket & 3/16 Allen key To Suit: Mazda MX5 NA/NB 1.6L & 1.8L 1989-2005
