3.5-Inch Cold Air Intake with 5-Inch Filter

It features large 3.5-inch intake piping and a 5-inch air filter, complemented by smooth 3-ply silicone couplers for a seamless transition. The design prioritizes a perfect fit by utilizing factory airbox mounts, ensuring a hassle-free installation that takes approximately one hour with basic hand tools. This intake system boasts significant performance enhancements, with flow bench testing demonstrating up to a 67% increase in airflow over the stock system. It incorporates a built-in velocity stack with a motorsport-inspired bellmouth shape to efficiently channel airflow, minimizing drag and turbulence. The system also amplifies engine and turbo sounds, creating a more exhilarating auditory experience. For those in harsh climates, an optional upgraded filter is available, featuring a 3-step filtration process with oil-treated pleats and a pre-filter sock to protect against contaminants. The intake also includes a stealth coolant line at no extra cost and works with or without SAI systems. Optional lid upgrades are available in polymer or carbon fiber for enhanced engine bay aesthetics. This product is 50-State CARB legal with EO Number D-838-1. It is important to note specific fitment exclusions: it does not fit Audi A3 engines equipped with a MAF sensor, which are commonly found in FWD models. For VW Arteon models, the optional carbon fiber lid is not compatible without washer filler neck relocation, and the IE Turbo Inlet Pipe upgrade (sold separately) is required. Additionally, some European models may require minor modification to the heat shield to clear a front-mounted crash sensor.
