The heatshield and inlet pipe is made from a glass filled polypropylene material that acts as an excellent heat deflection barrier to minimize inlet temps compared to no shield at all. The airbox is fed with fresh air from the frontal inlet ducting, rather than the surrounding engine bay, or radiator, keeping the system constantly fed with cool incoming air to satisfy the turbochargers needs under even the most demanding situations. The system literally installs in minutes too as it simply pops into place on the factory mounting pegs! And thanks to the open design, you'll hear the engine and turbocharger putting in work to make maximum power!
