These high quality manifolds are available in a satin finish or for just a few dollars more, a fully show polished version. Our polished versions are not a quick machine job. Several hours are spent by hand to truly make this a beautiful piece. This would cost $125.00 - $175.00 at a custom polishing shop. These not only look good but perform and fit just as well. These high performance aluminum intake manifolds deliver excellent all around performance. This dual plane 180° high rise design delivers outstanding performance across nearly the entire powerband. Optimum power from 1500 to 6500 R.P.M. retains good bottom end power and throttle response. Our manifolds are not sand cast but precision die cast in steel dies rather than sand molds like other manufactures. Sand cast manifolds can be vulnerable to internal core shifts which can cause misalignment between ports and heads or even air or coolant leaks. Each manifold is subjected to a thorough pressure test to assure a trouble free installation. The manufacturer is not new to the market. They have been making O.E.M. manifolds for automakers in both Japan and Europe for years. Extra features include mounting kit to ease installation, rear water crossover to aid in cooling, two extra NPT ports, crossover intake runners for more balanced length and nitrous bosses. Dyno tests have proven that this manifold equals or outperforms the equivalent top rated brands.
