Offered for sale is an intake manifold off of a C30A that has been massaged by ScienceofSpeed. The manifold's flashing has been ground away and then polished to optimize flow. The stock VVIS has been deleted and the manifold's center rib was professionally removed - all with the intent to improve top end HP. With the combination of aftermarket headers and exhaust, adding this manifold resulted in a peak of 269rwhp and 199rwtq on a stock engine. Intake leading to the throttle body was ported. Manifold runners left untouched (stock heads already flow extremely well). Fuel rails included with sale. Easy and effective bolt-on method to adding more HP and TQ.
$650 + shipping. SOLD
EDIT: for some reason some of the pics show upside down and editing them as rightside up does not seem to work. Turn monitor upside down?
