The Grams Performance modular small-port intake manifold for VW MK4 1.8T replaces the restrictive OEM unit with a two-piece design featuring a removable, rotatable plenum lid that allows easy disassembly, porting, and plenum volume changes. It accepts the stock bolt pattern with a 72mm opening, offers stealth mounting bosses, and suits lightly modified street builds as well as higher-horsepower turbo upgrades.
