The Grams Performance high-flow small-port intake manifold for VW MK4 1.8T is a modular, bolt-in replacement featuring a rotatable 1.85L plenum that allows driver- or passenger-side throttle body placement. It uses a stock bolt pattern with a 72mm opening, includes stealth mounting bosses for nitrous or methanol, and improves low- and mid-range response while supporting larger turbo builds.
