We’re proud to offer a hotside pipe with an bov flange to make for an easy install with more room vs the flange being on the coldside pipe. The aluminum piping is powder coated black and features a 2.5" diameter and smooth mandrel bends to provide ideal flow for higher horsepower setups. This kit is designed for use with stock style intercoolers, meaning it will fit with stock and most upgraded intercooler setups that work with factory piping. Silicone couplers and t-bolt clamps are included. Come with either a HKS or Tial flange.
