The Process West Silicone Y-Pipe (Part # PRW-PWSH003) is a direct replacement component supplied with Process West Top Mount Intercooler kits. Designed to ensure proper charge-air distribution, it plays a critical role in maximizing intercooler efficiency and maintaining consistent performance.
Engineered for precise fitment and reliable sealing under boost, this Y-pipe eliminates uneven airflow commonly found in generic aftermarket alternatives. The result is smoother, more balanced airflow across the intercooler core for improved throttle response and cooling consistency.
Note: This Y-pipe is designed exclusively for Process West TMIC systems. Compatibility with OEM or other aftermarket intercoolers cannot be confirmed.
