ECS Performance Supercharger Cooling System - S4 / S5 (B8/B8.5)
Due to the very high temperatures and constant heat cycling the OEM screws encounter, the flimsy plastic will become brittle over time. With almost 100% certainty, the stock screws will strip or break resulting in a coolant leak and an undrivable car if they are not replaced. ECS Tuning has you covered - we designed precision machined 7075-T6 billet aluminum bleeder screws that will last a lifetime!
