Product Information
A replacement intake whose whole lower air box, not just the lid, is enlarged by 60% to hold a custom filter with 40% more area (115 sq in against 82 sq in stock). Patterned secondary openings on the side away from the engine add air to the factory snorkel without raising turbo inlet temperatures, and the factory resonator is removed, so the system outflows the stock intake by 58% or more. Throttle response sharpens and turbo spool and blow-off become audible. On a stock or lightly modified car the extra flow brings no notable power gain; its value is removing the intake as a limit for builds with turbo and fueling upgrades.
