Designed with the serious motorsport competitor in mind, this kit brings the advantages of individual runner performance to many of today’s high output engines. These units breathe through four throttles into a runner designed to be a straight shot to the cylinder head where it joins the port at the optimal angle for maximum flow. All kits include adjustable fuel pressure regulator, fuel rail, billet linkage, full radius air horns and throttle position sensor (TPS). Supplied without injectors but fuel rails to accept several different types of injectors are available.
