Hand-fabricated for any H, B or K series application, King Motorsports' custom headers ensure that you're extracting every last bit of horsepower from your engine. Whether your engine is still in the original chassis, or swapped into any Honda/Acura platform, we'll build you a header that is a PERFECT FIT.

While some aftermarket headers increase power at either the low or high ends of the torque curve, or don't really do anything at all, a King Motorsports header built specifically for your application will not only give you the power where you need it, but also give an excellent torque curve.

After extensive R&D, King Motorsports is releasing our race-only front camber plates for the 06-08 Civic Si. Precision machined from 6061 aluminum, these plates offer up to 2 degrees of negative camber. Developed for the Koni Series, these camber plates do not have seats for the coil-overs, they require built-in hats and have only been tested with Koni coilovers.

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.
