ARP HotSide Intercooler Pipe Wrinkle Black 2013+ Ford Focus

Hot-side intercooler pipe designed for the 2013–2018 Ford Focus ST to open up charged-air flow and reduce airflow turbulence for more consistent boost delivery and responsiveness.

This ARP HotSide Intercooler Pipe in wrinkle black is a direct replacement for the restrictive stock hot-side plumbing on the Focus ST. The stock pipe is described as having excessive bends, a restrictive inner diameter and integrated muffling features that slow airflow and induce turbulence; the Mishimoto unit addresses these flow interruptions to restore a cleaner, less obstructed path to the intercooler.

• Purpose-built hot-side design — Replaces the stock hot-side pipe to provide a more direct charged-air route, which reduces turbulence and helps maintain steady boost response.
• Wrinkle black finish — Durable coating that provides corrosion resistance and a motorsports-style appearance suited to high-performance engine bays.
• Mishimoto engineering — Manufactured and supplied by Mishimoto, leveraging the brand’s focus on thermal and airflow performance to ensure component reliability under repeated use.
• Fitment for 2013–2018 Ford Focus ST — Specifically intended to address the known stock hot-side restrictions on this model range.

Why this matters: cleaner, less turbulent airflow into the intercooler supports more consistent charge temperatures and throttle response. For engines that rely on tightly managed boost and intercooling, reducing flow disruption on the hot-side plumbing contributes to predictable performance under load.

Key benefits

• Improved charged-air flow path compared to the stock unit.
• Reduced airflow turbulence for steadier boost behavior.
• Professional finish and corrosion protection for durability in service.
• Backed by Mishimoto’s focus on thermal and airflow components.
