Significantly increases airflow to your turbo producing improved horsepower and torque and cooler intake temperatures by drawing cold air through the inner fender. All aluminum 14 ga. construction features large diameter 4 in. piping with smooth aerodynamic bends. Improves intake air velocity, volume, and provides a more aggressive engine and turbo sound during acceleration. Our 4.8 in. turbo intake horn is the largest on the market providing a 20% air flow improvement over stock. High quality hardware, silicone boot, seals, and stainless steel t-bolt clamps ensure optimum durability and ease of installation. Removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with included hydrophobic pre-filter cover, to help keep your MAF sensor, turbo, and engine airways contaminant free.
