The kit includes a 4.8-inch turbo intake horn, which is advertised as the largest on the market, providing a 20% airflow improvement over stock. It also upgrades the restricted factory intercooler pipes with heavy-duty 3-inch diameter driver (hot) side and 3.5-inch diameter passenger (cold) side LMM intercooler pipes, with the passenger side improving airflow by 47% over stock. The bundle is made in the USA and includes high-quality hardware, silicone boots, seals, stainless steel t-bolt clamps, a hydrophobic pre-filter cover, CNC machined flanges with double o-ring seals, and a 3-inch Y-Bridge Kit.
