King Motorsports extended exhaust manifold studs allow for easier “slide-on” installation of most performance headers and help to support heavy-duty turbo manifolds. They are constructed of high strength alloy steel and also feature a corrosion resistant black nitride coating. These studs contrast a stainless steel header very well giving you a unique look under the hood. The kit includes ten steel cup-point studs and ten factory Honda flange nuts. The studs thread in and tighten with a 4mm allen wrench.
