Inline Pro M-series M11 K24Z3/7 Xtreme Duty head stud set 2009+ TSX Civic SI IP-HS-K24Z7

The Inline Pro Honda K24Z3 K24Z7 M-series M11 Extreme Duty head studs are made from the Highest Grade Premium American Alloy that have gone through rigorous heat treatment and testing. With a minimum tensile strength of 230kpsi, these are not prone to hydrogen embrittlement like the L19/H11 material and can be handled without worrying about failures. We use a True-beam design all the way through the length of the stud resulting in better clamping force and torque values (it's not necked-down or undercut like others). "Only settle for the Best!" The kit includes: Studs, nuts, washers, lube, and instructions. Applications: K24z3 and K24z7 engines ( found in the 2012-2015 Honda Civic SI and 2009-2012 Acura TSX)
