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. After the turbo, our Stage 3 kit also upgrades the restricted 2.5 in. diameter driver (hot) side intercooler pipe and leak-prone plastic / rubber passenger (cold) side pipe with WCFab's heavy duty 3 in. diameter 1-piece Driver (Hot) Side and 3.5 in. diameter Passenger (Cold) Side LMM Intercooler Pipes. Made in the USA from high strength, heavy duty 14 ga. aluminum tube with smooth, aerodynamic mandrel bends for increased durability and optimized flow. 3 in. Driver Side pipe includes high quality reinforced silicone boots and stainless t-bolt clamps for superior temperature resistance and boost pressure holding capabilities. 3.5" Passenger Side pipe improves air flow over stock part by 47%! Features CNC machined flanges with a double o-ring seals and an upgraded silicone hump boot in order to withstand higher boost pressures than the factory components to increase reliability and eliminate blown factory boots and horsepower robbing boost leaks. The final and key component of this bundle is our signature high flow 3" Y-Bridge Kit which replaces
