Akrapovič S-PO/TI/15 Slip On Line (Titanium) for Porsche models G 550 there is a heat shield

there is a heat shield attached to the side which blocks the hot air from the radiator and the alternator from directly impacting onto the carbon housing

It can be thought of as a large velocity stack - below is a diagram to show the comparison between our patented design and a regular intake system

the whole system is designed to give the smoothest flow—and the power and torque gains of the BMW with the combination of the Slip-On Line system and Evolution link pipe set are absolutely guaranteed

and also a significant change to the sound with the valves in the open or closed positions

This product is crafted from high-quality stainless steel
