It is made in the USA (California) and has a patent pending on it with stamp "Made in USA" on the die cast. The diameter of this plenum is 0.5" larger than stock plenum on each side. Go to utube and there are several dynos on the Porsches with this pelnum. You can even see how big this plenum is compare to stock. Pedro's Torque2 has identical design inside except with plastic glued to the stock pelnum. There is even patent pending on the design submitted by the IPD which is U.S. company.
