You are looking at the PERRIN Performance Throttle Body Coupler. Over time and mileage, your factory intercooler coupler can become dry and crack over time due to engine vibration, and like all things, it can become deteriorated due to the elements. This could cause boost leak issues which will certainly limit your performance.
